Abstract

A simple method GC-W previously proposed for estimating the Wilson parameters from pure-component properties has been adopted to predict the isothermal vapor–liquid equilibria of various binary systems consisting of non-polar and polar molecules. The prediction performances obtained are examined and evaluated in comparison with UNIFAC.
