Vapor-liquid equilibria for 1,1-difluoroethane plus acetylene and 1,1-difluoroethane plus 1,1-dichloroethane at 303.2 K and 323.2 K

Abstract

Isothermal vapor-liquid equilibria for 1,1-difluoroethane (HFC-152a) + acetylene and 1,1-difluoroethane + 1,1-dichloroethane (HCC-150a) were measured in a circulation type apparatus at 303.2 K and 323.2 K. The experimental data were correlated with the Peng-Robinson equation of state using the Wong and Sandler mixing rule, and the relevant parameters are presented.
