EXPLANATION. 

INTRODUCTORY. 

THE object of this book is to present, as far as lies in my power, 
a bibliography of all the measurements of the ionization con- 
stants and the electrical conductivity of organic compounds 
that have appeared in the periodical literature between the years 
1889 and 1910 inclusive, together with the values of the ionization 
constants, and certain values of the electrical conductivity measure- 
ments. Qualitative work is also included. Before the year 1889, 
little work of value at the present time was published. All that is 
of value is included here. From 1910 to the beginning of 1913, im- 
portant corrections that have come to my notice have been inserted. 
Beginning with 1910, full data of the entire periodical literature are 
published in the Tables Annuelles Internationales de Constantes et 
Donn^es Num^riques. 

Exceptions. The references to subjects chiefly of biological in- 
terest, as albumin, blood, sap, etc., are complete only for the last 
few years (roughly the last five or ten), but afford a means both of 
knowing where to get at the important work, which is all recent, and 
where to start in any more thorough search of the literature. 

The references to the resistance of substances such as rubber, wood, 
etc., have not been looked up. They are of value almost exclu- 
sively in connection with the question of electrical insulation. A 
few are given. There is a biological interest in some cases. 

The fact that the references to the literature of any compound or 
substance are not complete, is stated in the tables immediately after 
the name. 

References to the conductivity of inorganic compounds in organic 
solvents have not been looked up specially, though in cases where 
salt formation is to be expected they have been taken. When given, 
they will be found under the head of miscellaneous measurements, 
either separately from the references to organic compounds, or dis- 
tinguished from them by being placed in parenthesis. A few pages 
farther on, in the detailed description of miscellaneous measure- 
ments, will be given certain considerations of the question of com- 
bination of solvent and solute in making new compounds. 



6 EXPLANATION 

Additions. In the author list are given some artioles which con- 
tain only measurements of inorganic compounds, or matter which is 
theoretical. Such references are inclosed in parenthesis to dis- 
tinguish them, both in the author list and wherever else they may 
be used. The object of including them is to save time to persons 
who are interested only in original measurements of organic com- 
pounds. Experimental work in connection with theoretical con- 
siderations of dissociation and of electrical conductivity is almost 
invariably first carried on with inorganic compounds. Later work 
often refers to organic compounds for the sake of analogy, clearness 
or additional proof. In consequence of this, references are often 
met with, which are apparently to original work on organic compounds, 
when as a matter of fact the original article contains only quotations 
of experimental work on organic compounds, while the new experi- 
mental work is entirely on inorganic compounds. 

In the case of work on the conductivity of molten salts, which is 
quite recent, I have inserted a number of references to work on in- 
organic compounds, because experience has shown that these articles 
wiU be referred to, as soon as similar work on organic compounds be- 
comes common. 

In the tables, a number of references are given to work on the 
comparative strength of different compounds (measured in various 
ways), because to many chemists the chief value of the ionization 
constant of a compound, or of a measurement of its electrical con- 
ductivity, is to determine its strength as an acid or a base. When no 
quantitative data are available, 'qualitative data may be quite use- 
ful. Negative results, as the fact that a compound has no appreciable 
conductivity in hydrochloric acid, may be of use in determining the 
nature of a compound or as a guide for subsequent investigation. 

The statements in the tables always indicate when the work is of 
a qualitative nature, or when negative results have been obtained. 

A few measurements of inorganic compounds have been inserted 
for purposes of comparison. 

Method of search of the literature. Seventy-eight of the journals 
and about five thousand dissertations have been examined page by 
page; the other journals have been examined by index and table of 
contents, with page by page examination of articles that might con- 
tain information. The titles of articles usually give no indications 
of value, so omissions are to be expected. The omissions are most 
likely to occur in the case of measurements of the conductivity of 
salts, since these are frequently inserted very briefly, with no special 
mention of them in the text. 



EXPLANATION 



ARRANGEMENT. 

The book is divided into a set of tables arranged according to the 
names of the compounds, containing all the data that may be given, 
with a bibliography of all the references to each compound; a form- 
ula index to the compounds; a bibliography arranged according to 
the names of authors; a subject index to certain subjects; and a 
journal list giving the names of all journals examined with the number 
and date of the last volume examined. 

Order. Alphabetical order is used as a rule, but where the numeri- 
cal order is more natural (as in the case of mono- and di-, etc. com- 
pounds) that is used. With a few exceptions, due chiefly to recent 
practice, and the necessity of selecting a definite form or name in 
cases of dispute, Beilstein's Organische Chemie (3d edition), Richter's 
Lexikon der Kohlenstoff-Verbindungen and the International Cata- 
logue of Scientific Literature, have been used as guides and authori- 
ties. While I do not approve of a number of details in any one of 
these publications, it is obvious that if there is no yielding of personal 
prejudice all attempts at general uniformity will fail. Some incon- 
sistencies in names and formulae are due to the fact that no one 
authority can be followed throughout. 

In cases where more recent work has decided the composition or 
structure of a compound, such work has been accepted. It must 
always be remembered that the latest work on any subject is not 
necessarily the best, even when the newest theories and apparatus 
have been used. 



DETAILED DESCRIPTION OF THE DIVISIONS. 

TABLES. 
AiraBgement of the Compounds. 

While the arrangement of the compounds in the tables is alpha- 
betical, in order to bring together certain closely related compounds 
some exceptions are necessary, which are chiefly the use of customary 
names of isomers and of positions. Ortho-, meta- and para- com- 
pounds are placed in the usual order. Iso-, alio-, etc. compounds 
are placed after the normal compound, the prefixes (which are 
in italics) not being considered at all. The numerical order is 
followed in the case of mono-, di-, etc., derivatives of polybasic com- 
pounds. Immediately after each acid are given the amides, the 
anhydride and then the esters. On account of the small number of 



8 EXPLANATION 

compounds and the system of nomenclature used, there is little actual 
displacement due to these exceptions. Thus, iso-butyl alcohol comes 
immediately after wor-TO.-butyl alcohol, while iso-butyric acid follows 
butyric acid, but on account of the intervention of the butyric acid 
amides and esters it comes immediately after butyric acid propyl 
ester. The few other exceptions will be found by means of the cross 
references. In the case of the substituted amides there is an im- 
portant exception discovered too late for correction. When an 
anilino or toluidino radical is substituted for a hydrogen atom in the 
NH2 group, the compound is not mentioned at all under the head of 
the amides. Thus, acetanilide is not mentioned as acetic acid 
phenyl amide, nor is oxanilic acid mentioned as oxalic acid mono 
phenyl mono amide. 

Nomenclature. 

When an alphabetical arrangement is used, the place of any com- 
pound will vary according to the judgment used in the selection of 
the name, as in the case of methoxy-benzoic acid instead of hydroxy- 
benzoic acid methyl ether, and also according to the way in which a 
compound is regarded, as in the case of oxanilic acid which may be 
regarded as an amide. 

In the tables, when the choice lies between a common name and a 
systematic name, as gallic acid or trihydroxy-benzoic acid, most 
compounds with very familiar names are given under the common 
name, since few chemists except those working with organic com- 
pounds are able to remember the structure of the higher organic 
compounds. This use of common names has the disadvantage of 
separating isomers. The use of systematic names has two chief 
disadvantages. It requires a knowledge of structure. Apart from 
the dilEculty of remembering the structure of a number of com- 
pounds, our ideas of structure are constantly changing with increased 
knowledge. In the second place, there is no fixed use of systematic 
names. On the other hand, any consistent use of systematic names 
will bring together isomers, and sometimes closely related compounds; 
and the name will furnish some knowledge of the structure. 

Cross references are in general given only to the parent compound 
and not to the substituted compound. Thus, nitroterephthalic acid 
is not given (though a nitro-p-phthalic acid is in the tables), because 
under terephthalic acid is given the cross reference to p-phthalic 
acid. The formula index shows at once the name used in the tables. 

The names and the formulae of dyes are given as accurately as is 
possible under the circumstances, but any information concerning 
them must be used with caution. In most articles, on account of 



EXPLANATION 9 

the totally inadequate description given, and the ambiguous use of 
words, it is impossible to tell exactly what compound was used for 
measurement. Most commercial dyes are mixtures of compounds. 
If we assume that for any measurement the chief constituent of such 
a mixture has been isolated and purified, and is called in the article 
the pure dye, the structure may be in doubt, since different makers 
give the same name to dyes of different structure. Then in the case 
of the greater number of dyes, which are salts, it is quite impossible 
to tell which salt was the dye in question. There is some difference 
between the conductivity of a sodium and a potassium salt, or be- 
tween that of a hydrochloride, a sulphate and an acetate; yet as a 
rule, the descriptions do not state the particular salt which was used. 
In most cases, the statement that the pure dye base was used is mis- 
leading, for the statement really means that a salt of one compound 
was used, and not the salts of several compounds mixed — though 
as just mentioned, it is usually impossible to tell what the salt was. 
The same confusion of terms also exists in reference to the acid or 
base of a dye, here again a salt really being meant, and not an acid 
or a base. 

Hyphens and spaces are used to indicate particular groups, to 
avoid as far as possible the necessity of referring to the formulae. 

Numbers, letters and abbreviations used to indicate position are 
placed directly in front of the group or element which they affect. 
In a few cases, the termination of the name shows the character of 
the group, as " one " for the keto group in pyrazolone. In these 
cases the number follows in parenthesis. 

In the numbering of substituted cyclic compounds, the first sub- 
stituted group is always given the number one. Thus, in the sub- 
stituted benzoic acids, the carboxyl group is one; in the substituted 
anilines the amino group is one. In the toluic acids, the methyl 
group is one; but if they were regarded as methyl benzoic acids 
(derivatives of benzoic acid), the carboxyl group would be number 
one, and the number of the methyl group would vary according to 
the acid. 

The abbreviations C, N and (used instead of numbers) show that 
the substituting group is attached to the corresponding carbon, 
nitrogen or oxygen atom. Bz, shows substitution in the benzene 
ring; Py, in the pyridine ring. Carboxylic, in the name of an acid, 
shows the group COOH. For ambiguities in the use of the word 
hydro, see the following paragraph. The word nor, as in noropianic 
acid, shows that there is an unsubstituted compound, of which the 
substituted derivative (including esters and ethers as substituted 
compounds for the purpose of the present definition) has first been 
known, and named by the name which would naturally belong to 



10 EXPLANATION 

the unsubstituted compound. In this case, opianic acid is the dime- 
thoxy acid, noropianic acid is the dihydroxy acid. The word oxy 
means only oxygen, hydroxy being used to show the hydroxy! group 
OH. The word sulphinic shows the group HSO2. The word sulpho 
(as in sulphobenzoic acid) or sulphonic, shows the group HSO3. The 
word sulphone, as in sulphonediacetic acid, shows the group SO2. 

Differences in nomenclature causing confusion. In comparing the 
name of a compound described in an article in a journal, with the 
name used in other articles, or in standard works as those of Beil- 
stein and of Richter, or with the name in these tables, a number of 
differences in usage will be found, which may lead to error. It seems 
advisable to explain a few of the most common of these, which have 
caused a number of mistakes. 

In the case of compounds containing sulphur, there is so much 
variation in nomenclature, that the formula should always be ex- 
amined. Most chemists use sulphinic, sulpho, sulphone and sul- 
phonic, in the manner described in the preceding paragraph as used 
in these tables. The word thio, is used to show the replacement of 
any element by sulphur, or in making a name for a sulphur compound 
which is analogous to any non-sulphur compound. Thus, a thio- 
acetic acid may be CH3.COSH, or CH3.CSSH, or CHS.COOH. 

There is much ambiguity in naming compounds containing a sub- 
stituting group. Methyl-salicylic acid may mean methoxy-benzoic 
acid, or it may mean hydroxy-toluic acid, depending on whether 
substitution is in the hydroxyl group or in the benzene ring. Cyano- 
acetamide may mean cyanoacetic acid amide, or acetic acid cyanoa- 
mide. It is sometimes impossible to tell what compound is meant in 
cases such as these, unless the context supplies some means of identi- 
fication. There is a certain amount of error in statements concern- 
ing the measurements of organic acids by Ostwald, published in 1889 
(less than twenty-five years ago), simply from this sort of confusion 
of names. 

There is the same possibility of confusion, when the place of the 
substituting group is indicated in the name by a number or a letter. 
Thus, acridine in Beilstein has the nitrogen numbered 10, placed 
between carbons numbered 4 and 5. In Richter's Lexikon the 
nitrogen is also numbered 10, but is placed between carbons numbered 
1 and 9. In journal articles the starting point of the numbering 
varies, and the direction of the numbering, as in the direction of the 
hands of a watch or the reverse. This last variation of direction 
while of minor importance, is apt to create confusion when isomers 
which are mirror images are concerned. 

The word " hydro " is used in a most confusing manner. Thus, 
pyrrole is CiHsN. Tetrahydro-pyrrole (pyrrolidine) is naturally 



EXPLANATION 11 

C4H9N; yet it may be called hydro-pyrrole. In the same way in 
the case of other compounds, the dihydro- or hexahydro- compound 
of one man will be the hydro- compound of another. Furthermore, 
when substituting groups are present, the word hydro may be used 
to show the theoretical addition of hydrogen with subsequent sub- 
stitution of two atoms of hydrogen at that point. Thus, imideazole 
is C3H4N2. Parabanic acid, C3H2O3N2, is called triketo-tetrahydro- 
imideazole, though only two hydrogen atoms are present. In this 
case, four hydrogen atoms are supposed to be added; then, in the 
three CH2 groups, hydrogen is replaced by oxygen giving three CO 
or keto groups, leaving the fourth hydrogen attached to a nitrogen 
atom. This use of hydro is of convenience when type formulae are 
used, instead of printing formulae in the text, and is employed in 
Richter's Lexikon. 

Details of the arrangement under each compound. 

In order to aid identification or to show the purity of a compound 
for which any numerical data are given, the melting-point or boiling- 
point is given in the tables when it is stated in an article. This 
melting-point or boiling-point refers to the sample measured, and 
not necessarily to the most highly purified sample described in the 
article. In some cases the melting-point or boiling-point of a deri- 
vative (as a salt) may be given, when the article does not furnish 
such data for the pure compound. The position of these identifying 
data is directly after the ionization constant, or after the measure- 
ment of the conductivity. In many cases, where the original sup- 
plies no such data, I have looked up the mode of preparation, in order 
to make sure what the compound is. There is a good deal of reason- 
able doubt as to the position of substituted groups in a number of 
compounds, for instance in the toluidine sulphonic acids. 

Immediately after the name, are given (in parenthesis) the syno- 
nyms. These are inserted in some cases only for convenience in 
referring to the original articles, since the names used there have 
been abandoned. After the synonyms, comes the empirical formula, 
and when convenient the extended formula. Cyclic formulae are 
given only in the grouping on the pages directly in front of the tables. 
The extended formulae are intended to be of assistance, but not to 
represent the definitive structure, nor to exclude the possibility of 
tautomeric forms, floating double bonds, etc. 

The bibliographical references for each compound are arranged 
under definite headings which are not specifically named in the text. 
These headings are; (1) the specific conductivity of the pure com- 
pound; (2) the ionization constant; (3) the conductivity in aqueous 



12 EXPLANATION 

solution; (4) the conductivity in solvents other than water; (5) mis- 
cellaneous measurements, as the conductivity of mixtures with other 
compounds, conductivity under varying pressure, etc.; (6) the con- 
ductivity of the salts. 

In general, a reference with no explanation is either to the conduc- 
tivity in aqueous solution, or to the measurement of. the ionization 
constant. 

With the exception of old values of specific conductivity, which 
have been changed to make them correspond to the modern values, 
all data are given in the tables as in the original articles, rounding off 
decimals to tenths — a change that is actually of slight importance, 
since few of the measurements justify the use of the hundredths 
place. Values given in Siemens or mercury unit * have not been 
calculated to the corresponding values in reciprocal ohms for reasons 
which will be given later. 

Under each heading are given all the references in the bibliography 
bearing on that subject. These references are given as numbers in 
bold face type, corresponding to the numbers in the author list. 
Duplicate references, that is, references to publication of the same 
measurement in more than one journal, are not given in the tables. 
They may be found by means of the author list, in which all such 
duplications are given, the fact being noted after the title of the article. 
Thus, under the heading of the ionization constant of butyric acid 
at 25°, is given number 180. The author list shows that this is an 
article by Billitzer in the Monatshefte fur Chemie. After the title 
is the statement in brackets, " [same as 183] ", showing that the same 
measurement will be found in 183, which is an article published in 
the Sitzungsberichte der kaiserlichen Akademie der Wissenschaften 
(Wien). Either article gives the original measurement. In these 
cases of duplication, the reference number used in the tables is to 
the article in the most readily accessible journal. 

While as far as possible, no references to repetitions of the same 
measurement in different articles are given in the tables, it is impos- 
sible to avoid this altogether. Some of the measurements, in an 
article containing a number of measurements, may have been made 
by a person whose name is not mentioned. This person may after- 
ward publish these measurements in an article under his own name, 
with no mention of the fact that they have already appeared in print. 
Such cases have come to my notice. References to new measure- 
ments of the same compound or to measurements of different prepa- 
rations of the same compound, by the same observer, are given be- 
cause they tend to establish the accuracy of the first value. 

* The customary usage of regarding this as a unit of conductivity is fol- 
lowed, instead of speaking of it as the reciprocal of the unit of resistance. 



EXPLANATION 13 

When there is any advantage in one article, either from its greater 
accuracy, or from its more extended measurements, that reference 
number is placed first. In other cases the reference numbers are 
given in numerical order, though of course the number of an article 
from which any data are taken is placed directly after such data, 
followed by the numbers of the other articles. If the ionization 
constants or conductivity measurements in two articles are widely 
different, both are usually given, placing first the more rehable, and 
stating any possible explanation of such difference. But if the data 
in one article are evidently inaccurate, they are not given, though 
the reference number of that article is given. When there may be 
doubt from the name alone, what compound is referred to, greater 
weight is usually given to articles containing some means of determin- 
ing what compound was really measured, and how pure it was. In 
the case of isomers, when no identifying statements, such as melting- 
point, mode of preparation, etc., are made in an article, I have assumed 
that the most easily prepared or procured isomer was used. 

For all statements enclosed in brackets, I am responsible. 

Detailed description of the headings under each compound. 

1. Specific conductivity. As is customary, the old values are mul- 
tiplied by 10^ to make them comparable to the modern. 

The generalization that the specific conductivity of a compound 
is a safe guide to its purity (the purest sample having the lowest 
conductivity), is incorrect. It seems probable that the character of 
the impurity has a considerable influence, and that the closer it is in 
structure to the compound to be purified, the more difficult it is to 
detect very small amounts by the fall in conductivity. It is also 
probable that there is some actual effect of solute on solvent in many 
cases. Turner 1766, finds that conductivity alone is not a sure indica- 
tion of the amount of water in ethyl alcohol containing very small 
amounts of water. Foussereau 597, and Walden 1843, 1844, hold to 
the opposite view. Dutoit, Rappeport 491, find that the conductivity 
gives no absolute indication of the presence of very small amounts 
of impurity. See also 456, 1223, 1388 and 1389 in this connection. 

2. Ionization constant. The ionization constant, k, is calculated 

(a)^ 

from electrical conductivity measurements by the formula k = . 

(l-a)v 

In this, V is the volume in liters in which is dissolved one equivalent 

weight in grams of the compound, and a, is the degree of dissociation 

measured by . Text books must be consulted for a treatment 

A(oo) 



14. EXPLANATION 

of the inaccuracy of this formula in the case of bases, stronger acids, 
and polybasic acids in which the influence of the second hydrogen ion 
is felt at moderate dilutions; and also for the calculation of the con- 
stant by other means, as the hydrolysis of salts, etc. See also the 
Subject Index under the headings, Dilution Law, and Ionization 
Constant, for articles on the subject. The earlier authors follow 
Ostwald in expressing the value in decimals, and using a constant 
one hundred times k = K, to avoid unnecessary ciphers. In the 
tables the true constant k is used, expressed in powers of 10; thus, 
for acetic acid at 25°, k XlO^ =1.86. 

It is given for each temperature at which it was measured, with 
an abbreviated explanation of the method used for its determination, 
if this was not by the direct measurement of the electrical conduc- 
tivity of an aqueous solution of an acid or a base. When the value 
is greater than 10^, the value found by direct measurement of the 
electrical conductivity is generally chosen. When it is less than 10^, 
a value determined in some other way, by hydrolysis, etc., is given 
when possible; though in certain cases the value found by electrical 
conductivity is also given for the purpose of comparison with similar 
compounds, for which no method of measurement other than the 
electrical has been used. 

In the case of measurements by the conductivity method, the fact 
that the specific conductivity of the water of solution has not been 
subtracted in calculating the value of the constant is noted by the 
abbreviation aq., placed directly after the value of the constant, 
thus, l.Saq. The difference between the value corrected and uncor- 
rected, as a rule is less than five per cent, but may be sufficiently 
great to account for discordant results obtained by different persons. 

The statement that the value of the constant increases or dimin- 
ishes on dilution, is given for the purpose of attracting attention to 
the fact, since it may indicate the change from one isomer to another, 
or the presence of impurity. The cause of such variation is not always 
known. The assumption that a constant value not affected by dilu- 
tion is a criterion of purity, and that a steady diminution is always 
an indication of impurity, was first made by Ostwald 1371, who in 
the same series of articles rejects this criterion when it affects un- 
favorably the position of an acid in a series. Since that time classes 
of acids have been found, as the alkyl succinic acids, in which there 
is always a diminution in value on dilution. Noyes 1342 in the case 
of a regular diminution in the value of the constant of o-nitrobenzoic 
acid of great purity, states that this diminution means nothing of 
great consequence. See also 515 and 2018. For a detailed treat- 
ment see 1609. 

If the value of the constant is determined by conductivity measure- 



EXPLANATION 15 

ments, and there is an increase or diminution in the value on dilu- 
tion, the particular value chosen depends on the structure of the 
compound. In the case of a diminution in the value, the value at 
a dilution of about 32 liters is taken when possible, as being fairly 
accurate and affording a standard value for that compound com- 
parable with the greatest number of other compounds. If the value 
increases on dilution, in the case of the stronger amphoteric electro- 
lytes the value at a dilution of about 1024 liters is taken. This value 
is selected, because in a number of cases, as for instance the amino- 
benzoic acids, it corresponds fairly well with the value obtained by 
other methods. If the compound is a polybasic acid, the value for 
a lower dilution is chosen, when the influence of the second and third 
carboxyl groups is evident. In other cases, it has been impossible 
to follow any definite rules. 

The ionization constant for the second and third hydrogen and 
hydroxyl ions is also given, with an indication of the method by which 
it has been determined. 

In comparing the valiies of the ionization constant obtained by two 
different persons, certain general considerations have to be taken 
into account, as the purity of the compound (and sometimes its 
identity), the method employed and whether the value chosen as the 
best, is a mean value, or is extrapolated or otherwise derived from the 
measurements. If the method is that of the electrical conductivity, 
three factors must be especially considered; the temperature; the 
specific conductivity of the water (or other solvent); and the value 
used for A(oo). 

The temperature of the measurement is usually given, since its 
importance in chemical work has been recognized for such a long 
time. The ionization constant of most organic acids and bases 
increases with the temperature up to about 40° to 50°, and then 
diminishes as the temperature is raised still higher. See acetic acid 
for an illustration of this, and 1332 and 1341 for measurements cov- 
ering a wide range of temperature. When no temperature is stated 
in an article, it is safe to assume that it was either 18° or 25°, except 
for compounds like the diazo compounds which decompose readily at 
ordinary temperatures. 

The value of the specific conductivity of the water of solution gives 
an indication of it3 purity. The purification to water having a specific 
conductivity of 2 to 3 X lO"' at 25° is so easy, that for a number of 
years, measurements have been made with water at least as pure as 
that. The question of whether this conductivity is to be subtracted 
in whole or in part or not at all, is still a matter of dispute, the cor- 
rection made varying with the individual opinion. The difference 
made by this correction may be of some importance; thus in the case 



16 EXPLANATION 

of a--iso-phenylacetic acid at 25°, the ionization constant (multiplied 
by 10^) is 3.76 with no correction, but is 3.67 when corrected for the 
conductivity of the water. This water had a specific conductivity 
of 1.4x10"' at 25°. See 1533 for the details of this measurement. 

The value used for A(oo) depends chiefly on the unit of conduc- 
tivity, and on the values used for the equivalent conductivity of the 
hydrogen and hydroxyl ions; to a much less degree, on whether it is 
calculated from the measurements made, or is taken from a set of 
tables. For almost all measurements made before the year 1898, 
the Siemens unit was used. Since that time, either this unit or the 
reciprocal of the ohm then proposed by Kohlrausch is used, the 
tendency being more and more to use the reciprocal ohm. For 
acetic acid, at 25°, the value of A(oo) is about 364 in Siemens unit, 
and 388 in reciprocal ohms, the mean factor for the conversion to 
reciprocal ohms being 1.066. The error of using one unit for the 
other is rarely made. It is due to the false assumption that all values 
for the specific and molar conductivity published in the last ten years, 
are in reciprocal ohms. The value for the molar conductivity (really 
in Siemens unit) will be taken from some article, the value for A(oo) 
in reciprocal ohms wiU be taken from a table, and the ionization con- 
stant calculated from this mixture will naturally differ from any that 
has been known before. 

The value for the equivalent conductivity of the hydrogen ion is 
not yet settled, there being a difference of about six per cent between 
the extreme values given for 25°, that is 340 and 365 in reciprocal 
ohms. There seems to be no doubt at the present time, that this 
value varies with the concentration; and it is possible that other 
factors may also influence it. See Kendall, Jour. Chem. Soc. 101, 
1275, (1912), for a review of the subject with new data, and Lewis, 
Jour. Am. Chem. Soc. 34, 1631, (1912), for certain theoretical con- 
siderations. The value for A(oo ) of acetic acid at 25°, will vary from 
381 to 408, in reciprocal ohms, depending on the value used for the 
hydrogen ion. Taking the molar conductivity at a dilution of 32 
liters as 9.2, this gives the ionization constant (multiplied by 10^) 
as 1.86 in one case, 1.64 in the other. A difference as great as this 
is often used as a basis for showing that a compound has a particular 
structure, or is a new compound. Up to the year 1910, practically 
all the organic acids have had their ionization constants calculated 
with a value of A(oo) in which the equivalent conductivity of hy- 
drogen is from 345 to 348, occasionally a little higher, but in no case 
high enough to make such a difference from other measurements, as 
has just been shown possible. But the use of this much higher value 
for the hydrogen ion is becoming more common, and may lead to 
some mistakes. 



EXPLANATION 17 

In the case of bases, the equivalent conductivity of the hydroxyl 
ion, makes a corresponding difference. But there have been practi- 
cally no changes made in it by new measurements, since the year 1894. 
It is to be noted that Bredig 271, used an older value in calculating 
the ionization constants of the bases published by him in that year, 
and stated that with the present value the ionization constants are 
about sixteen per cent too high. In the tables they are given in their 
uncorrected form, with a statement of the correction. In Kohlrausch 
and Holborn's Leitvermogen der Elektrolyte, they are given uncor- 
rected, though the values of the conductivity are calculated from the 
original form to reciprocal ohms. 

The values of A(oo) calculated from measurements of the salts of 
acids, made at the same time and under the same conditions as the 
measurements of the acids, do not vary enough from the values pub- 
lished in the tables of Ostwald, and of Lund6n* to cause any trouble. 
They ought to be more accurate for their purpose, than the table 
values. See White and Jones 1968a, for an illustration. 

In determining the ionization constant by methods other than the 
direct measurement of electrical conductivity, the value used for the 
ionization constant of water often enters into the calculation. The 
value most frequently used is the old one for 26°, k^ = 1.2x10""- 
If a measurement is made at 25°, the error from the use of this value 
is small, but the farther the temperature departs from 25° the greater 
is the error. At 0°, the constant of water is about 0.1 instead of 1.2, 

so that the substitution of this higher value in the equation k =— ^, 

X 

where x is the hydrolysis constant, will give a value for the ionization 
constant which is about ten times too large. 

Calculation of the ionization constant by factors for various groups 
and for different positions of the same group, gives results that are 
not reliable. In some cases, the agreement is good, in others bad. 
There is not yet sufficient knowledge to make such a calculation of 
much value except where the constants of closely related compounds 
are known. 

3. Conductivity in water. As a rule the only data given under this 
head are the values for the molar conductivity at 25°, for dilutions 
of 32 and 1024 liters (or as close to these dilutions as possible) and 
the value at infinite dilution. Occasionally the values for the cor- 
responding dilutions at 0° are also given. In the case of the more 
important compounds, the references are arranged according to 

* Lund^n 1143 and Affinitatamessungen an schwachen Sauren und Basen, 
gives a table of the values of A( oo ) calculated for acids containing from 
twelve to thirty atoms, at temperatures from 0° to 50°. 



18 EXPLANATION 

temperature. When only one measurement of a compound has been 
made and the ionization constant determined from this, the tempera- 
ture is given only under the head of the ionization constant, unless 
there is some intervening statement, such as the ionization constant 
of the second hydrogen ion. If all the references to the conductivity 
are desired, it is advisable to look up those given under the ioniza- 
tion constant as determined by the measurement of conductivity, 
as well as those given under this heading, though in general such 
references are given under both headings. 

The values given for the molar conductivity are not reduced to a 
common unit, nor corrected for the specific conductivity of the water 
used, because in many articles there is a lack of data for making such 
reductions. Experience shows that when corrections are made in 
some cases and not in others, persons using a set of tables will as- 
sume that the correction is always made and that the values are com- 
parable. Reference to the author list (which is necessary to find out 
the name of the person corresponding to the key number) shows at 
once whether an accurate comparison can be made with the values of 
other compounds. In articles published up to the year 1898, it is 
safe to assume that the unit is the Siemens unit. The factor to con- 
vert this into the reciprocal ohm varies from 1.063 to 1.069 for most 
measurements, the mean value 1.066 being sufficiently accurate for 
most purposes. For details see Kohlrausch, Holborn, Diesselhorst 
1002, or Kohlrausch and Holborn, Leitvermogen der Elektrolyte. A 
few of the old measurements made in a special unit have been cal- 
culated to Siemens units when given in the tables, and a note of this 
change made both in the tables and in the author list. When the 
author list does not show the unit of measurement, it can often be 
found if a value of A(oo ) is given for an acid, by comparing this value 
to that of other acids, or with the values in tables. A comparison 
of the value of the conductivity at a given dilution with that (in a 
known unit) of some similar compound at the same dilution is useful. 
But it may be quite misleading, unless the compounds are near each 
other in an homologous series. 

4. Conductivity in solvents other than water. No numerical data 
are given. The references to inorganic solvents are given first, then 
to organic solvents. No distinction is made between pure solvents 
and solvents diluted with water. Reference to the subject index in 
which such a distinction is made, will usually settle this point. When 
alcohols are used as solvents, many measurements often cover the 
entire range from the pure solvent to very high dilutions or to pure 
water. 

A number of researches of a qualitative nature have been made with 
these solvents, especially with the inorganic solvents. The results 



EXPLANATION 19 

of such researches are expressed in the tables with a qualifying clause 
to show that they are not quantitative, thus, " In ethyl alcohol, small 
cond." When, for any solvent, quantitative as well as qualitative 
measurements have been made, the references to the quantitative 
work are always given first, then the references to the qualitative 
work prefixed by the qualifying clause to show their nature. 

5. Miscellaneous measurements. Under this heading are given 
references to a variety of measurements, most of them to the con- 
ductivity of the compound in solutions containing other compounds. 
In consequence, the heading in the tables usually begins, " Cond. 
with". 

These measurements of mixtures have been made for a great variety 
of purposes and can not conveniently be subdivided in any brief way. 
For instance, under acetic acid they are divided into conductivity 
with inorganic compounds — acids, bases and salts ; and with organic 
compounds — acids, bases, salts and other compounds. In the case 
of an acid, the measurement of the conductivity with a base may be 
made to show the number of carboxyl groups, or to show the effect 
of the presence of small or large amounts of the salt of the acid, or 
whether any salt formation actually occurs. If the measurement is 
of a solution to which an alcohol is added, the object may be to show 
the effect of adding a non-electrolyte, or to show if any esterification 
occurs. In other cases, as of a phenol in a solution containing iodine, 
the measurement may show that oxidation or substitution occurs. 

These cases of mixtures of compounds can not strictly be separated 
from the cases of a compound in a dilute aqueous solution of a non- 
aqueous solvent, though in practice such a distinction is usually made. 
The references to the conductivity of mixtures of organic compounds 
are usually given under all the compounds in question. 

The references to the compound as solvent, are to the conductivity 
of the compounds dissolved in it, or to complexes that may form. 
Thus, under acetic acid, the first reference to the acid as solvent gives 
the conductivity of sodium acetate in the pure acid, and in aqueous 
solutions of various strengths. The same reference is also to be 
found under the sub-heading of conductivity with organic salts. The 
references to the conductivity of compounds as solvents, are not 
complete for the cases when an inorganic compound is the solute. 

The nature of the other miscellaneous measurements is obvious 
from the brief explanation, as, " under pressure," etc. 

6. Salts. These are arranged, first as inorganic salts, then as or- 
ganic, in alphabetical order. 

The data given, when possible, are the molar conductivity at 25°, 
for dilutions of 32 and 1024 liters, of the sodium (or potassium) salts 
of acids, and the hydrochlorides of bases. This selection is made, 



20 EXPLANATION 

because these salts are most often made, and the conductivity of 
their solutions measured, and these dilutions are used to determine 
the basicity of acids. In a number of cases, the only data of a con- 
ductivity measurement given in the original article is the.difference 
between the conductivity at 1024 and 32 liters. In the case of very 
readily hydrolyzed salts, when the measurement is also made with 
repression of hydrolysis by excess of acid or base, this measurement 
is also given. 

The number of radicals in the salt is indicated by the figure pre- 
fixed. Under oxalic acid, for instance, Na.A is the mono-sodium or 
acid salt, while 2Na.A is the di-sodium salt. Under acetic acid, 
Ca.2A, is the calcium salt, requiring two acid radicals. 



FORMULA INDEX. 

This is arranged in the customary manner. For each compound 
is given only the name used in the tables, the synonyms being given 
in the tables. A number of salts are inserted for convenience, especi- 
ally when the acid or base has not been made, or isolated in pure form. 
In general, salts are to be found by looking up the acid or base from 
which they are derived. 

AUTHOR LIST. 

The names of the authors are arranged alphabetically. Prefixes 
not beginning with a capital letter, as de and von, are not considered 
in the arrangement. A few errors may be present, on account of 
the apparent indifference of some persons as to the initials which 
belong to their names. The English names beginning with Mac and 
Mc are sometimes quoted in foreign literature without the prefix, 
thus. Coy instead of McCoy. 

. Each name is preceded by a number which is used throtighout the 
book for all reference to that particular article. After the name, is 
given the abbreviation of the journal title, the series number in 
parenthesis, the volume number, page number and date. Then 
follows the name of any person who is said to have made a measure- 
ment described in the article, thus, 11 . . . (1898). Meas. E. Cohen. 
A cross reference is given from the name of the individual making 
the measurement; thus, under the letter C, is Meas. E. Cohen, see 11. 
If only a part of the measurements were made by a person other than 
the author, the name is preceded by the sign ^ , thus Meas. Smith. 
The name of the measurer is so often given with scrupulous accuracy 
in the literature, that it has been necessary to burden the bibliog- 
raphy in this way in order to make known that such measurements 



EXPLANATION 21 

were not overlooked. On the other hand, there are many cases in 
which there is no doubt that the author did not make the measure- 
ments, but there is no way of finding out who did make them. 

When an author has published articles in different journals, the 
journals are arranged in alphabetical order in two divisions, giving 
first the more accessible. Under each journal, the articles are ar- 
ranged chronologically. For an illustration, see the references to J. 
Walker. 

The title of the article is given in full, translated into English in 
the case of titles in Russian. If the same article, or a summary is 
printed in some other journal, the full title is not repeated, only 
enough being given to indicate that it is the same as in the first 
reference. 

Articles in parenthesis contain no original measurements of the 
ionization constant or of the electrical conductivity of organic com- 
pounds. 

In brackets immediately after the title, is given information as to 
whether the numerical data in the article are republished in some 
other journal. Such statements do not refer to the text. The un- 
qualified statement, " same as ", indicates that the numerical data 
are the same in both articles. The unqualified statement, " given 
in ", indicates that there are additional numerical data, or additional 
compounds measured, in the article referred to. When it does not 
take too much space, the difference between the two articles is stated 
in the bracket. The most common difference is that one will give 
only the ionization constant, while the other will give full details of 
the measurement from which the constant was calculated, with 
tables of the conductivity at different dilutions, in the case of con- 
ductivity measurements. This difference is always noted in the 
bracket, by some such statement as, " k, but not A is given in ". 
Information of other kinds is also given in brackets, as to whether an 
article contains only qualitative work, etc. In a certain number of 
cases, it is impossible to tell whether the same numerical data have 
been republished in different articles or whether new measurements 
of the same compounds have been made. Some duplications un- 
doubtedly have been given in the tables on this account. 

In the tables and in the subject index, in cases of repetition of 
measurements, only one key number is given, referring to the most 
accessible journal. Examination of the author list will show whether 
any other article contains the same numerical data. 

After the title are given (when the original supplies them) certain 
data of use in comparing constants, or for further information. These 
are; the temperature, with extremes if several different temperatures 
have been used; the unit of conductivity; and the specific conduc- 



22 EXPLANATION 

tivity of the water of solution, with a note of whether this conduc- 
tivity was subtracted from the conductivity of the solution, indicated 
by the abbreviation, " sub." Thus, x aq. =1 Xl0~*; sub. 

SUBJECT INDEX. 

The headings in this index depend so much upon the individual 
point of view, that in using it, it is advisable first to look through 
the headings and to consider the definitions and illustrations. 

In cases of doubt, or in cases open to legitimate difference of 
opinion, the reference is given under all possible headings. 

For the sake of brevity, consecutive references by the same author 
are sometimes given inclusively, thus 60-63, instead of giving each 
number separately. These inclusions are never used if the numbers 
cover more than one name. 

JOURNAL LIST. 

The journals examined include all the important journals, and as 
many of the minor journals (and dissertations) as has been possible. 

Most of the articles in the Journal of the Russian Physico-chemical 
Society have been examined by Mr. G. Torossian, and the statements 
translated by him. They have been checked by me, as far as a very 
limited knowledge of the language allows. 

The arrangement is alphabetical for the chief words in the title, 
particles such as, and, de, der, etc., not being regarded. This sepa- 
rates distinct publications of the same society, as Proceedings, and 
Memoirs, but does not necessitate an exact knowledge of the title. 

The volume number (and when necessary the page number or 
division number) and the date of the last volume examined, are 
given immediately after the title. 

When a title is preceded by the sign -^ , as M Annales de, etc., the 
journal is not complete through the year 1910, either because it has 
been impossible to examine one or more volumes, or because the 
volume for the year 1910 has not been issued. A note of the number 
or of the date of missing volumes is given. 

The titles are those in use at the present time. If any important 
change in a title has been made, the fact is noted, and a cross refer- 
ence is given. 

Different libraries adopt different methods of numbering volumes 
when a publication appears in several series, some using continuous 
numbers, others following the numbers of each series. Different 
methods of dating are also used, when a volume covers more than one 
year, some giving the date of the year of publication, others the dates 



EXPLANATION 23 

of the years included in the volume, others the date of the appearance 
or of the reading of the last article in the volume — a date that may- 
be several years earlier than the date of publication. These differ- 
ences are a source of some confusion in references in the literature. 
In addition to these difficulties, some societies issue a number of 
publications, which may be bound separately under individual titles, 
or in various combinations under various titles. 

Journals are sometimes referred to by the name of a past or present 
editor, as Drude's Annalen instead of Annalen der Physik. Cross 
references have been given to all the cases that have come to my 
notice. 

The names of journals which have contained no data are inserted 
in order to show exactly what journals have been examined. 

At the end is added a list of the authors of articles in the Journal 
of the Russian Physico-chemical Society, arranged chronologically, 
with the page numbers of the articles. This is given because the 
variations in names due to different systems of transliteration, make 
checking of references to this journal slightly difficult. 

BOOKS. 

Much of the numerical data published in the journals has been col- 
lected and republished in various forms in text-books and mono- 
graphs. Three of these are very useful. Taking them in chrono- 
logical order; Das Leitvermogen der Elektrolyte, Kohlrausch and 
Holborn, (1898), contains fairly complete data of the ionization con- 
stants, and of electrical conductivity in aqueous solution (with all 
values calculated to reciprocal ohms, but no values of A(tx)) given). 
Bredig's constants for the bases, as previously noted, are about six- 
teen per cent too high. The Conductivity of Liquids, Tower, (1905), 
contains data of the specific conductivity of pure liquids, and some 
data of the conductivity in solvents other than water; and also some 
data of conductivity in aqueous solution, published between the years 
1898 and 1905. Affinitatsmessungen an schwachen Sauren und 
Basen, Lund6n, (1908), gives tables of the best values of most of the 
ionization constants published from 1889 up' to 1908, corrected 
(when necessary) for the values of the ionization constant of water 
at various temperatures, with a table of the values used in making 
these corrections. Bredig's ionization constants for the bases are 
given with no comment that they are too high. A number of tables 
of value are also given, though little numerical data of electrical con- 
ductivity are given, except as illustrations. All three books contain 
some bibliography. Die Theorie der elektrolytischen Dissociation, 
Abegg, (1903), also has some numerical data of value. Volume 1 of 



24 EXPLANATION 

the Tables Annuelles Internationales de Constantes et Donn^es 
Num6riques, containing complete numerical data of ionization con- 
stants and of electrical conductivity published in the periodical litera- 
ture for 1910 has been issued. Volume 2 for the year 1911, is in 
print, but at the time of writing has not been published.* 

GENERAL. 

The difficulty of a search through the literature for all references 
to subjects which are rarely indicated by the titles of the articles, can 
be appreciated only by those who have done that sort of work. Omis- 
sions are to be expected, chiefly I should suppose, in the case of the 
measurements of the conductivity of salts. 

When an article has been found, there is sometimes doubt and 
sometimes entire uncertainty as to what the author really means. 
The confusion due to nomenclature has already been mentioned. 
There is also confusion from diversity in the use of symbols. For 
the ionization constant, a small k or a capital K is used indifferently 
(and occasionally an italic k), although in the majority of cases a 
capital K (following the usage of Ostwald) stands for 100k. When 
numerical data of the measurement are given, it is possible to find 
out by calculation, whether k or 100k is meant. But the simple 
statement that k (or K) is a given quantity, leaves the case in some 
obscurity, unless the compound is one of an homologous series, in 
which the values of the ionization constant for members of the series 
close to it are known. It must always be remembered, that the 
rules given for calculating constants by means of factors for certain 
groups, and positions, while satisfactory in many cases, are quite 
unreliable in many other cases. 

In the case of the ionization constant, the use of some letter other 
than a Roman k, may lead to confusion, unless there is a direct state- 
ment that this constant is meant. For instance, the Greek letter 
kappa, is frequently used as a symbol for specific conductivity. The 
statement, " electrical conductivity shows that x =0.14 ", may mean 
that the specific conductivity is 0.14, or it may mean that the ioniza- 
tion constant is this quantity, for an italic k may have been written, 
which was incorrectly printed. 

Almost every letter in the English alphabet, and many of the 
letters of the Greek alphabet have been used as symbols for specific 
conductivity, molar conductivity and degree of dissociation. The 
use of such a symbol with no explanation, leaves in doubt which of 
these three quantities was intended, unless there is some way to 
check it from preceding articles, or from the context. 

* It has been issued in July, 1913. 



EXPLANATION 25 

It is interesting to note that in general the obscurity varies with 
the chief occupation of the author. At one extreme is the chemist 
chiefly interested in organic work. He describes his compound 
accurately, gives the formula, and some data, as melting-point, etc., 
by which it may be identified. Then he says, " The conductivity of 
this acid I have found as follows: fc = 1.4 x 10""." But he means the 
ionization constant, not the specific conductivity, and gives no data 
of conductivity values at all, in spite of his direct assertion that he 
does. It is left to the reader to find out what he means, and to check 
off as far as possible the value of the constant, in order to know 
whether k or 100k is meant. At the other extreme is the chemist 
chiefly interested in physical chemistry. He states that the com- 
pound he is using is methylsalicylamide; and that it is pure because 
it came from Kahlbaum, and the melting-point remained unchanged 
after five recrystallizations from alcohol. All the definitions and 
data relating to the measurement of the conductivity are given 
clearly. But there may be grave doubt as to what the compound is. 
The name is ambiguous, for the position of the methyl group is not 
stated. No formula is given, and no melting-point. Even the fact 
that this unknown melting-point remained unchanged after recrystal- 
lization is no proof of purity, for many cases are known of mixed com- 
pounds of definite melting-point which crystallize unchanged from 
one solvent and can be broken up only by crystallization from a dif- 
ferent solvent. 

In the determination of the ionization constant by methods other 
than the direct measurement of electrical conductivity, certain other 
obscurities may be present. 

The identity of the compounds, I have verified as far as possible 
by a careful examination of the formula, method of preparation, 
melting-point or any other data available in' the original. The 
values for the ionization constant have been checked off, whenever 
the necessary data have been given in the original, making possible 
the correction of some mistakes due to errors in calculation. 

Numerical data taken from publications generally inaccessible, as 
dissertations, are given more fully in the tables than the data from 
accessible publications. More numerical data and more explicit 
subdivisions of headings are given in the case of important compounds, 
than of unimportant compounds. 

A small number of compounds are given in the tables, which are 
mentioned neither in Beilstein, nor in Richter's Lexikon. Since the 
measurements of their conductivity are described by thoroughly re- 
liable men, it seems reasonable to suppose that such compounds were 
actually made, but that, for some reason, the description of them has 
never been published. 



26 EXPLANATION 

Since the object of publishing bibliography is the saving of time to 
others, I have used much freedom in certain methods of presentation. 
Thus, the name Tschugaeff is familiar to many chemists. It is used 
in the author list under this form, and not under the form required by 
the system of transliteration employed. The cross reference is 
therefore from the unusual to the better known form. This same 
principle of using well known forms, has been employed in a variety 
of other cases. A liberal use of cross references and some repetition 
have been necessary to cover aU cases. 

The reliability of the work published in the journals is usually 
sufficient, but its accuracy is not as great as is supposed. This is 
due both to lack of definite knowledge of certain theoretical considera- 
tions necessary in making various corrections, and also to the uncer- 
tainty of some of the fundamental values. The limitations of the 
methods employed are fairly well understood, though there is a tend- 
ency to exaggerate the accuracy of some of these methods, as for 
instance colorimetric methods, especially when used in the case of 
very weak compounds. 

Our knowledge of the action of the solvent on the solute is still 
imperfect, and the corrections for such action, even when water is 
the solvent, are either matters of opinion, or are not known at all. 
Various other corrections are still uncertain, because our knowledge 
of the subject is not yet perfect. 

There are three fundamental values, the equivalent conductivity 
of the hydrogen ion, and of the hydroxyl ion, and the ionization con- 
stant of water, one of which enters into almost every calculation of 
the ionization constant of any compound. It must be emphasized 
again, that any considerable change in one of these values affects 
considerably the value of all the ionization constants calculated with 
its aid. A recalculation of practically every constant that has been 
published up to the present time, may be necessary when these three 
values are finally established. 

The rounding off to tenths of the numerical data printed in the 
tables has saved much space and added greatly to the accuracy of 
the comparison of the figures with the originals, while the error in- 
volved is too slight to be of consequence, except in a few cases. 

The apparently excessive number of abbreviations is due to the 
fact that all abbreviations are given, even those so commonly used 
that they are not usually explained, such for instance, as o for ortho. 
Most of the abbreviations, including those of the titles of journals, 
can be understood without looking up the full meaning. 

Details are given in this explanation which will appear to many to 
be unnecessary. But together with the abbreviations, they make it 
possible to understand anything that is in this book, without the

special search for the usage of the time or place or school or author, 
so often necessary for the understanding of what has been printed; 
for, in addition to changes due to the growth of knowledge, there are 
changes of fashion in science as well as in the world at large. In the 
case of nomenclature, it has often happened that an author proposes, 
but Beilstein disposes of new ideas. 

Against two criticisms I have no defense. The first is, that this 
is an overelaboration of an unimportant subject. The second (which 
is not contradictory to the first) is, that sufiScient numerical data are 
not given to make the table of compounds of much value. Other 
criticisms could be answered, for many results are not yet positively 
established. Theories and compounds that have, " forever been 
swept from the literature," have at times come back with an in- 
creased knowledge, while others that have been firmly established by 
physical chemistry, have been greatly modified or have disappeared. 
Our understanding of the dissociation theory has changed so much 
by degrees, that the statement of James Walker made two years 
ago,* " We are justified in attributing the fact that acetic acid is a 
weak acid, whilst trichloracetic acid is a powerful one, rather to the 
properties of the un-ionized substances than to the properties of the 
ions," is an upholding of the dissociation theory and not an attack 
on it, as would have been the case twenty years ago. 

Serious physical disability coming when the greater part of the 
material for this bibliography was collected, has made necessary 
rather awkward insertions, has delayed its publication, and pre- 
vented as full a presentation of the subject as I had hoped. No 
information at all has been given about apparatus and methods. The 
references to the conductivity of inorganic compounds in organic 
solvents are incomplete, though recent work makes it clear that in 
many cases some complex is formed. I have been unable to make 
some changes in arrangement, which would have given a more sys- 
tematic presentation. The references often contain more informa- 
tion on the subject than might be gathered from the headings under 
each compound, for great detail in subdivision of headings is obvi- 
ously out of place in a bibliography of this sort. While its use will 
be limited to a small number of persons, I trust that the work as it 
stands will be of sufficient value to justify a very dreary and un- 
pleasant task. 

Thanks are due to Dr. Wilder D. Bancroft, Dr. Alice F. Blood and 
Dr. James F. Norris for advice, and to Dr. Olin F. Tower for per- 
mission to use some tables from his book.

CYCLIC FOEMULAE. 

THE formulae given here are mostly type formulae, that is the 
formulae of compounds selected as the simplest members of 
various groups of compounds. The position of substituting 
groups is indicated in the name of a compound by numbers, the num- 
bers corresponding to those used in the formula of the type compound. 

The presence of CH is shown by an angle. Any other combina- 
tion of elements is given in full. Valences are not represented. 
Tautomej-ic formulae are not given as a rule, nor the formulae of alka- 
loids and dyes. For the purpose of comparison with original articles, 
and with older names, various letters which represent position are 
given as well as numbers. 

In the tables the name of the type compound may be given in the 
first name, as in dimethyl-parabanic acid, or it may be given in one 
of the synonyms in parenthesis, as in the case of alizarin (1,2-dihy- 
droxy-anthraquinone) . In a more complicated case, as in the case of 
anilopyrine (which is referred to pyrazole), iminopyrazole is also given 
as a type formula to show the manner of attachment of the imino 
group. In certain of the types no numbers are shown, as in cyclo- 
butane, because it is immaterial where the numbering begins. In such 
a case, the position of numbered substituting groups is readily found. 

For a detailed treatment of certain doubtful or unsettled points con- 
cerning names, see the heading " nomenclature," in the explanation.

TABLES 

THE compounds are arranged alphabetically, except where the 
numerical order is more natural, as in the case of mono- and 
di- derivatives. Immediately after each acid are given the 
amides, the anhydride and then the esters. Iso-, alio- etc. compounds 
are placed after the normal compound, the prefixes not being con- 
sidered. 

The headings under each compound are: (1) the specific conduc- 
tivity of the pure compound; (2) the ionization constant; (3) the 
conductivity in aqueous solution; (4) the conductivity in solvents 
other than water; (5) miscellaneous measurements; (6) the conduc- 
tivity of the salts. 

Numbers in bold face type are bibliographical key numbers, re- 
ferring to the corresponding numbers in the author list. When the 
same measurements are published in more than one journal, the key 
number is to the most accessible article. In the author list, after the 
title of this article are given references to the less accessible articles. 

When the value of the ionization constant has been determined by 
measurements of the conductivity of the compound, no statement of 
the method is made except for emphasis; other methods are shown by 
an abbreviation in parenthesis. The abbreviation aq., placed after 
the value, shows that the conductivity of the water has not been 
subtracted in calculating the value. Second, etc., k, means the 
constant of the second, etc. H or OH ion. 

Numerical values of conductivity, unless otherwise stated, are for 
aqueous solutions; with the obvious exception of those for the specific 
conductivity of the pure compound, which can always be recognized 
because neither concentration nor dilution is given. If all the refer- 
ences to the conductivity in water are desired, look up also the refer- 
ences given under the ionization constant, for in some cases these have 
not been repeated under the heading, conductivity in aqueous solution. 

The dilution in liters is given in parenthesis in its proper place. 
Thus, A(32) = 9, shows that the equivalent conductivity at a dilu- 
tion of 32 liters is 9 reciprocal ohms, or whatever unit may be used. 

The values given for the equivalent and the molar conductivity are 
in the unit used in the original article, unless otherwise stated in the 
table. Reference to the author list wiU show what this unit is. 

When different values of the ionization constant or of the conduc- 
tivity are compared, it is advisable to read in the explanation the 
precautions necessary for a proper comparison.

Diazo compounds. 

At the present time the nomenclature of diazo compounds is not 
settled. Their structure also is still a matter of dispute. 
The most general usage is to speak of the compound as a 
diazo body, while its salt is a diazonium salt, e. g. diazo- 
benzene, benzenediazonium chloride. This is done regard- 
less of the question as to whether there are always two 
isomers, one a neutral body (diazo) the other a salt-forming 
body (diazonium). In these tables there is, therefore, a 
lack of uniformity in the position of diazo compounds, in- 
creased by the fact that the cyanides, chlorides, etc. are 
regarded by some as separate compounds and by others as 
salts. A duplication of references has been used to cover 
such differences of opinion, since our present knowledge 
does not seem to justify any final conclusion.

Fischer, Freudenberg, Ber. Deutsch. Chem. Ges. 45, 915, 
2709, (1912) have made a synthetic pentagaUoyl-glucose 
[called by them pentadigalloyl-glucose in some places] 
C4iH32026=C6H706[C6H2(OH)3CO]5 which gives the reac- 
tions of purified tannin (=tannic acid). Nierenstein, Ber. 
Deutsch. Chem. Ges. 43, 628, (1910) finds that the formula 
is Ci4Hi209=(OH)3C6H2.CHOH.O.C6H2(OH)2.C02H. Pan- 
iker, Stiasny, Jour. Chem. Soc. 99, 1819, (1911) show by 
partition measurements the probable presence of a carboxyl 
group. The purity of the preparations used in making the 
following measurements is rather doubtful under the cir- 
cumstances. It is probable that tannins from various 
sources will be found to contain isomeric or homologous 
tannic acids, instead of all containing one acid.

AUTHOR LIST. 

The names are arranged alphabetically. Prefixes not beginning with a 
capital letter, as de, van and von, are not considered in the arrangement. 

Each article is preceded by a number in boldface tjrpe, used as a key num- 
ber in all references to that article. 

Notes in brackets after the title, refer only to numerical data and not to 
the text. Thus, [Quoted], shows that such data have been quoted from 
some other article; [Same as], shows that such data are the same in another 
article, the number of which is given. Occasionally a brief explanation is 
given, as Qualitative, Indicators etc. 

The name of a person who made measurements described in the article, 
follows the date of the journal. When only part of the measurements were made 
by such a person, the name is preceded by the sign # , thus, § Meas. Smith. 

When an author has pubUshed articles in different journals, the journals are 
arranged in alphabetical order in two divisions, giving first the more accessi- 
ble. Under each journal the articles are arranged chronologically. 

Articles enclosed in parenthesis contain no original measurements of the 
ionization constant or of the electrical conductivity of organic compounds.
