Abstract

The coefficients of estimation equations required to evaluate the interaction parameters between unlike molecules from pure–component properties are reported for alcohol+hydrocarbon binary systems. By using the equations, the Wilson parameters can be estimated, and the vapor–liquid equilibria (VLE) of the mixtures can be predicted on the basis of a previously proposed method.
