摘要：

Vapour-liquid equilibria (VLE) were determined in the polystyrene + toluene system under isothermal conditions at 363.15, 373.15, and 383.15 K using an improved all-glass microebulliometer with circulation of the liquid phase for the dynamic measurement of total pressure over liquid mixtures. The experimental data were correlated using the UNIQUAC-free volume model and the applicability of three known predictive models was tested. It was found that prediction of VLE using the GC-Flory equation of state, the UNIFAC-vdw-FV and the Entropic-FV model are of the same quality.
