Isothermal vapor-liquid equilibrium data for the binary system difluoromethane (HFC-32) + pentafluoroethane (HFC-125) were measured at temperatures from (265.15 to 303.15) K by the circulating method in this work. The vapor-liquid equilibrium data were correlated by the Peng-Robinson equation of state combined with a linear combination of the Vidal and Michelsen mixing rule and nonrandom two-liquid model. The results reveal that the correlated data are in a good agreement with the experimental values.
