Abstract
Infinite dilution activity coefficients have been calculated for 24 sy stems including highly non-ideal and nearly non-ideal using original, modified UNIFAC and UNIFAC-FV models. The calculations are compared wi th experimental results. The performance of the models in predictions and the significance of free volume effects on solvent activities in s olutions containing small compounds are discussed.
