Vapor Pressures and Thermodynamic Properties of Benzene-Cyclohexane Solid Mixtures

Abstract

A modified dew point method for measuring vapor pressures of condensed phases is applied to solid mixtures of benzene and cyclohexane. From the measured vapor pressures, activity coefficients and excess Gibbs energies are derived. Much less accurate information about excess entropy and excess enthalpy is obtained. A comparison is made with the known properties of liquid mixtures of the same molecules.
