Abstract

Isothermal vapour-liquid equilibrium data are presented for binary mixtures of 1,1,2,3,3,3-hexafluoro-1-propene with either propane or n-butane in the (312-343) K temperature range. The experimental phase equilibrium data were measured using an apparatus based on the "static-analytic" method. The experimental data were correlated with a thermodynamic model comprising of the Peng-Robinson equation of state with the Mathias-Copeman alpha function, the Wong-Sandler mixing rule, and Non-Random Two-Liquid activity coefficient model. The model provided a very satisfactory correlation of the experimental data for both binary systems. (C) 2015 Elsevier B.V. All rights reserved.
