ABSTRACT
Binary vapor-liquid equilibrium data were measured for the difluoromethane (HFC-32) + dimethyl ether (DME) and 1,1,1,2-tetrafluoroethane (HFC-134a) + dimethyl ether (DME) systems at temperature from (313.15 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 Peng-Robinson equation of state using the Wong-Sandler mixing rules.
