Vapor-liquid equilibria of the carbon dioxide (CO2)+2,2-dichloro-1,1,1-trifluoroethane (R123) system and carbon dioxide (CO2)+1-chloro-1,2,2,2-tetrafluoroethane (R124) system
Binary vapor-liquid equilibrium data were measured for the carbon dioxide (CO2)+2,2-dichloro-1.1,1-trifuoroethane (R123) system and the carbon dioxide (CO2)+1-chloro-1,2,2,2-tetrafluoroethane (R124) system at temperature from 313.15 to 333.15 K. These experiments were carried out with a circulating-type apparatus with on-line gas chromatography. The experimental data were correlated well by Peng-Robinson equation of state using the Wong-Sandler mixing rules. (c) 2006 Published by Elsevier B.V.
