AZEOTROPE-LIKE COMPOSITIONS OF PENTAFLUOROPROPENE AND 1,1,1,2,2-PENTAFLUOROPROPANE

摘要

The present invention provides azeotrope-like compositions of 1,1,1,2,2-pentafluoropropane (HFC-245cb) with either the Z isomer of 1, 1, 1, 2, 3-pentafluoropropene (HFO-1225yeZ) alone or with mixtures of the E and Z isomers of 1,1,1,2,3-pentafluoropropene (HFO-1225 yeZ and HFO-1225 yeE) and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agent compositions, and aerosol propellants, and in process for separating azeotrope-like mixtures.
