Abstract
Vapor-liquid equilibrium data for the ternary system alpha-pinene + be ta-pinene + (S)-(-)-limonene were determined at 80.0 kPa and 101.3 kPa in a modified miniature Othmer still. Parameters of the Wilson, NRTL, and UNIQUAC equations were calculated with the aid of a Nelder-Mead t echnique to minimize an objective function based on the total pressure . Predictions of the ternary data by parameters determined using binar y data were made. The results were compared with the predictions of th e UNIFAC method.
