摘要：
Isothermal vapor-liquid equilibrium data of the binary system difluoromethane (HFC-32) + pentafluoroethane (HFC-125) were measured in the temperature range from 268.15 K to 308.15 K at 10 K intervals and in the composition range from 0.1 to 0.8 mole fraction. Temperature, pressure, and compositions of the liquid and vapor phases were measured with a circulation type apparatus. The experimental data were correlated with the Carnahan-Starling-De Santis, Peng-Robinson, and Redlich-Kwong-Soave equations of state.
