Gas-liquid critical properties of the cycloalkanes and their mixtures

Abstract

Gas-liquid critical temperatures of the C₅-C₈ cycloalkane mixtures and the vapour pressure and densities of cycloheptane and cyclooctane near the critical region are presented. Deviations of the reduced vapour pressure and density of the cycloalkanes from those of the inert gases have been calculated. The deviations have been found to be similar for all four cycloalkanes. The critical temperatures of the mixtures have been discussed in terms of the van der Waals "one fluid" mixture theory.
