Abstract
The vapor-liquid equilibrium for difluomethane + pentafluoroethane (R-32 + R-125) was measured by the static method in the temperature range between 283 K and 313 K. The vapor-liquid coexistence curve near the critical point was measured by the observation of the meniscus disappearance. The critical temperatures and critical densities of a 30 mass % R-32 and a 60 mass % R-32 mixture were determined on the basis of the saturation densities along the coexistence curve in the critical region. In addition, the critical locus for the R-32 + R-125 mixture is correlated as the function of composition.
