Wilson parameters were estimated from solubility parameters and molar volumes. Namely, the interaction parameters due to attractive forces were evaluated from the solubility parameters and molar volumes predicted by the group contribution method of Fedors. The vapor-liquid equilibria (VLE) of several binary systems (hydrocarbon binary mixtures, binary systems containing ethers, binary systems containing ketones, ethanol + hydrocarbon systems and water + polar molecule systems) were correlated by use of these Wilson parameters, in which the interaction parameters between unlike molecules were adopted. The interaction parameters were determined by using VLE data and the correlation of the parameters obtained was attempted with the pure component properties such as solubility parameters and normal boiling points.
