The prediction of the vapor‐liquid equilibria of vegetable oil‐hexane mixtures is studied. Activity coefficients are calculated by the UNIFAC model. Different entropic contributions to activity coefficients from the literature are analyzed. These modifications improve the performance of the original UNIFAC model in vapor‐liquid equilibrium calculations.
