Vapor−Liquid Equilibria for the Systems Difluoromethane + Chlorodifluoromethane, Difluoromethane + Dichlorodifluoromethane, and Difluoromethane + Chloromethane at 10.0 °C

Yun Whan Kang, Kun Yong Chung

Abstract

Isothermal vapor−liquid equilibria for the three binary systems (difluoromethane + chlorodifluoromethane, difluoromethane + dichlorodifluoromethane, and difluoromethane + chloromethane) have been measured at 10.0 °C. The experimental data for the binary systems are correlated with the Wilson equation and the relevant parameters are presented. The difluoromethane + dichlorodifluoromethane system forms a minimum boiling azeotrope, but the others do not.
