✦ Synopsis
A&Wad-Perturbed-hard-cham theory IS extended to Include chemical dlmenzatlon eqmhbrta for strongly polar molecules Usmg four adlustable molecutar parameters, the extended theory gwes good representation of the PVT properties of polar ffulds, mcludmg water, alcohols and ketones For nonpolar fltnds only three adjustable parameters are required Straightforward extension to muttures requues one charactensttc bmary parameter for "physical" mteractlons and, for polar-polar nuxtures. another for "chemical" mterachons The combined "physical and chemical" theory grves good representation for a variety of binary mixtures contammg polar and/or nonpolar components Particular attention IS gwen to the systems methanol-water and ethanol-water where good results are obtamed at pressures rangmg from atmosphenc to over 100 bars
