In a series of our studies, GC-W (Group-Contribution method based Wilson equation) has been successfully proposed. It has been ascertained that GC-W is useful to correlate VLE (Vapor-Liquid Equilibria) with the interaction parameters ε_12 and ε_21 between unlike molecules. Further, the empirical equations have been developed to estimate ε_12 and ε_21 by using solubility parameters and normal boiling points of pure components. In this study, the characteristics of the interaction parameters ε_12 and ε_21 between unlike molecules have been considered and discussed for various specified binary mixtures.
