摘要：

Vapor-liquid equilibrium conditions (p-T-x-y) of the binary mixture chlorodifluoromethane (R22) + dimethyl ether (DME) have been measured for the first time along six isotherms (three subcritical and three supercritical). The mixture forms a negative (maximum boiling) azeotrope which persists to the critical line. Direct observations were made of points on the critical line. The two lower temperature isotherms are fitted to a temperature-dependent Redlich-Kister excess Gibbs free energy model. The equal area method has been used to test the thermodynamic consistency of the two lower temperature isotherms. A brief description of the apparatus is given.
