Phase Liquid–Vapor Equilibria and Thermodynamic Properties of Solutions of Binary Systems of N-Propylbenzene–N-Alkylbenzenes
摘要
Abstract
The phase equilibria of liquid–vapor solutions of four binary systems formed by n-propylbenzene and n-alkylbenzenes have been studied. It has been established that the contributions of intermolecular interactions to the Helmholtz energy for solutions of constant molar concentrations formed by n-propylbenzene and n-alkylbenzenes linearly and fractionally depend on molar mass of n-alkylbenzene in the homologous series. The corresponding equations have been derived.
