Thermodynamics of polar liquid mixtures

Abstract

Thermodynamic perturbation theory is used to study the phase equilibrium behaviour of liquid mixtures in which the molecules have appreciable electrostatic intermolecular forces. The influence of such forces, as well as that of charge overlap (shape) forces, on the phase diagram is briefly discussed. This is followed by a comparison of theory and experiment for the excess properties of the mixtures Xe + HCl, Xe + HBr, Xe + C₂H₄ and Kr + C₂H₄.
