Abstract
We measured vapor–liquid equilibria (VLE) and critical locus for the system of difluoromethane (HFC32)–pentafluoroethane (HFC125) ranging from 318.15 to 349.15 K. Composition differences between vapor and liquid phases on the P–( x– y) diagram were very small. The critical locus can be classified as type I behavior according to the system of van Konynenburg–Scott. The system of HFC32 and HFC125 is unusual in that the larger component in molecular weight has a lower critical temperature and vapor pressure than the smaller component. Using binary interaction parameter m ij expressed as a linear function of composition and temperature, we obtained excellent correlation of the experimental data with an extended BWR equation of state.
