Induction effects in polar-polarizable liquid mixtures

We generalize Wertheim's renormalized perturbation theory for polar, polarizable fluids to mixtures. The generalized theory is used to calculate the thermodynamic excess functions and phase equilibria for a variety of polar/non-polar and polar/polar mixtures. The results demonstrate the importance of including induction effects in a proper description of mixtures, and show the superiority of the 1-R form of the theory (which includes higher order multibody effects) over the 0-R form. Comparisons are made with experimental data for methyl chloride/xenon mixtures.
