Abstract

Henry's law constants for 24 different systems have been determined using UNIFAC and related group contribution models. The results obtained from original, modified and free-volume effect UNIFAC models are compared with experimental results. Empirical relationships for the temperature-dependency of Henry's constant for the chloroform(1)-water(2) system are also determined.
