(Vapour+liquid) equilibria of the {carbon dioxide+pentafluoroethane (HFC-125)} system and the {carbon dioxide+dodecafluoro-2-methylpentan-3-one (NOVEC~(TM)1230)} system

摘要

Binary (vapour+liquid) equilibrium data were measured for the {carbon dioxide+pentafluoroethane (HFC-125)} system at temperatures from 313.15 K to 333.15 K and the {carbon dioxide+dodecafluoro-2-methylpentan-3-one (NOVEC~(TM)1230)} system at temperatures from 313.15 K to 343.15 K.These experiments were carried out with a circulating-type apparatus with on-line gas chromatography.The experimental data were correlated well by the Peng-Robinson equation of state using the Wong-Sandier mixing rules.
