ABSTRACT

(Vapor + liquid) equilibrium (VLE) data for binary system of (a-pinene + p-cymene) and ternary system of {a-pinene + p-cymene + (S)-( )-limonene} were measured at 100.7 kPa using the modi?ed Ellis equilibrium still. The VLE data are thermodynamically consistent. Parameters of the binary system for the four solution models Liebermann Fried, Wilson, NRTL, and UNIQUAC were calculated by referencing least squares method to minimize an objective function based on the total pressure. The ternary system data were predicted with the parameters of Liebermann Fried model obtained from the pertinent binary systems. The predicted bubble-point temperature and the vapor composition for the ternary system were in good agreement with the experimental results. Smooth representations of the results are used to construct constant excess Gibbs free energy contours on Roozeboom diagrams
