摘要：
Isothermal vapor-liquid equilibrium data for the binary mixture of pentafluoroethane (HFC-125) + propane (HC-290 or R-290) at six temperatures between (268.15 and 313.15) K were measured by using a circulation-type equilibrium apparatus. The experimental data were correlated with the Carnahan-Starling-De Santis equation of state (EOS) and the Peng-Robinson EOS using the Wong-Sandler mixing rules. It was confirmed that the data calculated by these EOSs have good agreement with experimental data. In this system, strong positive azeotropic behaviors were observed over the whole temperature range studied here.
