摘要

To overcome the limitations of the existing UNIFAC-type group-contribution models presented in part 1, two empirical approaches are presented. They both involve adjustment of the pure- compound parameters of the compounds involved which, while reducing the general character of the group-contribution approach, can lead to very satisfactory results when applicable. Such an approach is successfully applied to the correlation and prediction of mutual solubility data in water/hydrocarbon mixtures.
