On the gas—gas equilibria of polar—non-polar binary mixtures from a polarizable hard-sphere dipole model

Abstract

Perturbation theory is applied to a polarizable hard-sphere dipole model mixture. It is shown that for increasing values of the reduced polarizability of the non-polar component. gas—gas equilibria of the first and second kind can be described for a polar—non-polar binary mixture. However for the latter case, critical lines do not show the minimum in temperature observed in real systems. Comparison between theoretical and experimental results are given for HeNH 3 and ArH 2O mixtures.
