AZEOTROPIC
DATA—II
ts. 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Chemicals Co. for supplying unpublished data for inclusion in the tables.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 Α-component and under each Α-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 Α-component, the next lowest order as B-component, and so on.
With a few exceptions for common chemical names, nomenclature in the
tables follows the Chemical Abstracts nomenclature system.
