Values of heats of mixing are reported for methanol, n-butanol, and n-octanol with carbon tetrachloride at 25 °C. The experimental results are combined with data from other sources and an analysis of the excess thermodynamic functions for carbon tetrachloride solutions of methanol, ethanol, n-propanol, n-butanol, and n-octanol in terms of Barker's theory of solutions is described. The behavior of these systems can be reproduced fairly well by the Barker model.


The perturbation treatment of the orientational forces between non-spherical molecules proposed by Cook & Rowlinson (1953) is extended to mixtures by using the theory of solutions put forward by Longuet-Higgins (1951). The thermodynamic functions and the equation of state of such mixtures are expressed in terms of the intermolecular forces and the properties of one pure component. Expressions are derived for the excess (or non-ideal) thermodynamic functions which are compared with the experimental results on the four solutions, benzene+ cyclohexane , benzene+carbon tetrachloride, benzene + ethylene dychloride, and cyclohexane + carbon tetrachloride. The agreement between theory and experiment is improved by taking account of the orientational forces.
