摘要：
Refrigerant compositions include mixtures of 1,1,2-trifluoroethane and a second component wherein the second component is (CF3)2NF, (CF3)3N, N(CHF2)2(CF3), N(CH2F)(CF3)2, SF5CF2H, SF5C2F5, HFC-236ca, HFC-236cb, HFC-236ea, HFC-254cb, HFC-254eb, HFC-263fb, HFC-272ca, HFC-281ea, HFC-281fa, HFC-338mf, HFC-4310mee, butane, cyclopropane, isobutane or propane. The invention also relates to azeotropic or azeotrope-like compositions which comprise admixtures of effective amounts of 1,1,2-trifluoroethane and (CF3)2NF, (CF3)3N, N(CHF2)2(CF3), N(CH2F)(CF3)2, SF5CF2H, SF5C2F5, HFC-236ca, HFC-236cb, HFC-236ea, HFC-254cb, HFC-254eb, HFC-263fb, HFC-272ca, HFC-281ea, HFC-281fa, HFC-338mf, HFC-4310mee, butane, cyclopropane, isobutane or propane to form an azeotropic or azeotrope-like composition.
