Abstract

The method of calculating the limiting activity coefficients of components was developed and illustrated by a number of examples. Isothermal binary data on the compositions of the solution and vapor coexisting phases were fitted to the Porter, Margules, Van Laar, Wilson, Redlich-Kister, and NRTL interpolation equations. In this method, nonideality of a vapor phase is directly taken into account and the composition of the azeotrope in the system, if exists, may be calculated.
