Application of the Theory of Regular Solutions to Binary Phase Equilibria. I. Method of Application to Binary Liquid Equilibria

Abstract

The same expression for the correlation of compositions in mutual equilibrium of two liquid phases as that which is immediately obtained from the empirical relations used by Cox and Herington was derived thermodynamically. The method has been given in such a manner as to represent the solubility curve for a binary liquid system symmetrically and to estimate the interchange energy from the mutual solubility data by applying the theory of regular solutions.
