Abstract:	A four-parameter group-contribution model (UNIFAC) has been developed for the prediction of heats of mixing of non-electrolyte mixtures. Both the UNIFAC and AGSM models are evaluated over a wide range of temperature dependencies of the group interaction parameters. The UNIFAC model has been chosen over the AGSM model and an optimum parameter-temperature relationship has been established. Adopting the optimum temperature dependency, group inter-action parameters have been calculated using UNIFAC for the prediction of four types of mixtures: n-Alcohols/n-Alkanes; Benzene/n-Alkanes; Nitriles/n-Alkanes; Amines/n-Alkanes.
