Maximum boiling azeotropic composition and azeotropelike compositions.

摘要

The invention provides an azeotrope-like binary composition comprising not less than 65 mole percent of 1,1,1-trifluoroethane and not more than 35 mole percent of pentafluoroethane. The invention further provides a refrigerator in which an azeotrope-like binary composition comprising not less than 65 mole percent of 1,1,1,-trifluoroethane and not more than 35 mole percent of pentafluoroethane is used as a refrigerant.
