A simple method GC-W for estimating the Wilson parameters from pure-component properties alone has been adopted to predict the vapor–liquid equilibria of binary systems at reduced pressures. The various binary systems containing non-polar and polar molecules have been studied. The prediction performances obtained are examined and discussed in comparison with UNIFAC.
