Table of Dielectric Constants of Pure Liquids Arthur A. Maryott and Edgar R. Smith The "static" dielectric constants of more than 800 substances in the liquid state were critically examined and tabulated ini concise form. Tihe table consists of three sections: A, Standard Liquids; 13, Inorganic liquids; and (', Organic Liquids. An indication of the probable accuracy of the data is given. Wherever feasible, a simple analytical fuinction is employed to express the variation of dielectric constant with temperature.

1. Introduction This tabulation of the dielectric constants of pure liquids is part of a program for a critical examination of the data of physics and chemistry, sponsored by the National Bureau of Standards in cooperation with the Committee on Tables of Constants and Numerical Data of the National Research Council and the Commission on Tables of Constants of the International Union of Chemistry.

The preparation of additional tables of the dielectric constants of gases, solids, aqueous and nonaqueous solutions and mixtures, and of

dipole moments is in progress.

The assemblage and evaluation of the data at the National Bureau have been made entirelySbsecond

of Standards with the assistance of 'I. during the preliminary stages.

Temperature is the only variable considered explicitly. Usually the pressure is atmospheric or insignificantly different with respect to its effect on dielectric constant. However, where data are listed at temperatures above the normal boiling point, the pressure corresponds to the vapor pressure of the liquid unless indicated otherwise in a footnote. quency is given in a footnote.

suggestions from M. E. Hobbs of Duke University, C. P. Smyth of Princeton University, and the Committees of the National Research Council and International Union of Chemistry are gratefully acknowledged. The compilations of P. Debye and H. Sack (Tables de Constantes et Donn6es Numdriques XI, Fasicule 2, 1931-34; XII, Fasicule :32, 1935-:36 and earlier volumes of Tables Annuelles), International Critical Tables, and Landolt-Bornstein Tabellen have been useful in checking the tables for accuracy and completeness. In several instances data have been obtained from the Tables of Dielectric Materials, volume III, prepared by the Laboratory of Insulation Research, Massachusetts Institute of Technology, Cambridge, Mass., 1948.

Section A contains values of the dielectric constant at selected temperatures for 10 substances that are recommended as reference liquids because of their chemical stability, availability, and the reliability of the data. The probable 'accuracy is estimated to be about 0.2 percent for methanol and nitrobenzene and about 0.1 percent in the remaining cases. Values of a or a are included for interpolating or for extrapolating over a limited range of temperature without materially altering the accuracy. Additional (lata for these substances are contained in sections B or C.

2. Description of the Table

2.3. Chemical Formulas and the Order of

The table consists of three sections: A, Standard Liquids, B, Inorganic Liquids, C, Organic Liquids. The (dielectric constants are intended to be the limiting values at low frequencies, the so-called "static" values. Data obtained at such high frequencies that anomalous dispersion was evident are not included. In questionable cases the fre-

Listing Substances Formulas for the inorganic substances are written in the usual manner. The order of listing compounds in section B is alphabetical according to the symbols for the elements in these formulas with consideration also given to the number of atoms of each kind.

INTRODUCTION

Formulas for the organic compounds are written with carbon first and hydrogen, if present, second. Symbols for all remaining elements then follow ill alphabetical sequence The arrangement of these compounds in section C is determined first by the number of carbon atoms, secondliv b% tile nulnber of hydrogen atoms, and finally by thle symbols for the remaining helements in alphal)etical order.'

2.4.

Estimated Accuracy of the Values of Dielectric Constant

Values of dielectric constant recorded in sections B and C have an estimated accuracy indicated by tie number of figures retained. (a) Values listed to four figures are considered probably accurate to 0.5 percent or better, (b) Values listed to three figures are considered probably accurate to 2 percent or better. (c) Values listed to two figures are considered probal)ly less accurate than 2 percent. However, where lack of detailed information makes any assignment of accuracy difficult or where excessive rounding off is undesirable, an additional figure is often retained which is not to be counted in determining the probable range of accuracy. Such figures are printed in smaller type as subscripts. They are also retained when significant with respect to variations of dielectric constant with temperature or to differences between isomeric or other closely related compounds in a series of measurements. These estimates of accuracv were assigned arbitrarily after considerations of the investigators' apparatus and methods, precision, probable purity of materials, and comparisons, where possible, with the results of others, Exception is made for certain series of polymers (e. g., polysiloxanes) which may he represented by the general formula (X). or .4(X).H. where n = 1, 2. 3. etc. The location of all compounds of such a series is determined hy the formuia corresponding to n-l.

2.5. Variation of Dielectric Constant With Temperature Where

feasible,

the variation

of dielectric

constant with temperature is represented by one

of the following equations:

g1 0 et-Log, 0 f,-a(t'-t

(2)

where •,, 1, and a (or a if the value is followed immediately by a in parentheses) are specified in the table. Occasionally other equations are indicated in footnotes. The range of temperature over which the equation is considered satisfactory appears under the heading t,, t 2. This range was chosen such that the deviations between the calculated and reported values of e are not greater than one-fourth of the accuracy assigned to E. Thus if E is listed to four figures (discounting figures in smaller type), the equation fits the reported data to 0.13 percent or better over the specified range of temperature; and, if e is listed to three figures (discounting figures in smaller type), the equation fits the data to 0.5 percent or better. Values of e falling outside of this range of temperature are listed at selected temperatures. 2.6. Literature Reference in Table All tabulated data are based on the references indicated by numbers not enclosed in brackets. The numbers refer to the bibliography following the table. Some additional references not employed for one reason or another are enclosed in brackets. These latter references are not intended to be complete with regard to data published for each substance but have been selected on the basis that they probably merit consideration in any revision of the tabulated data.
