It includes revised data on systems in the original table plus new data on azeotropes, nonazeotropes, and vapor-liquid equilibria collected since 1952. No attempt has been made to evaluate the data. Where appreciable differences occur in data from different sources, more than one set of data is recorded. Where minor differences occur, only one set of data is recorded, but all references are cited.
A brief description is included for calculating azeotropic data for immiscible systems from vapor pressure data.
In general data have been obtained from the original literature. Where the original literature was not available, data have been taken from Chemical Abstracts. In a few instances, data have been taken from collections of azeotropic data in handbooks, review articles, and so forth.
Acknowledgment is made to Commercial Solvents Corp., The Dow Chemical Co., Eastman Chemical Products Inc., Farbenwerke Hoechst, Imperial Chemical Industries Limited, Minnesota Mining and Manufacturing Co., and Union Carbide Chemicals Co. for supplying unpublished data for inclusion in the tables.
The tables are arranged in the same manner as the previous volume. This is based on empirical formula as in Chemical Abstracts except that all inorganic compounds are listed first, alphabetically by empirical formula.
For a given binary system the lower order component according to empirical formula is chosen as the А-component and under each А-component the B-com-ponents are also arranged according to empirical formula. For ternary and quarternary systems the same arrangement is used, using the lowest order formula as А-component, the next lowest order as В-component, and so on.
With a few exceptions for common chemical names, nomenclature in the tables follows the Chemical Abstracts nomenclature system.
