VAPOR–LIQUID EQUILIBRIA FOR THE BINARY MIXTURE OF CHLORODIFLUOROMETHANE+ DIMETHYL ETHER SYSTEM

摘要

Binary equilibrium data were measured for the (chlorodifluoromethane (R22) + dimethyl ether (RE170)) system at temperatures from 283.15K to 303.15 K. These experiments were carried out with a circulating-type apparatus including on-line gas chromatography. This refrigerant blends showed azeotropic behavior and the raw data were correlated well by the Peng–Robinson equation of state using the Wong–Sandler mixing rules.
