    摘要: Compositions of difluoromethane, 1,1,1,2-tetrafluoroethane, and 1,1,2,2-tetrafluoroethane are useful as refrigerants, aerosol propellants, heat transfer edia, gaseous dielectrics, fire extinguishing agents, expansion agents for polymers such as polyolefins and polyurethanes, and as power cycle fluids.Near azeotropic compositions comprise admixtures of effective amounts of difluoromethane and tetrafluoroethane to form a near azeotropic composition. Such compositions are useful as refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, refrigerants, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.
