摘要:
The present invention provides hydrofluorocarbon compositions suitable for use in a wide range of applications. The compositions of the present invention tend to be soluble in hydrocarbon lubricating oils, and thus, are especially useful in replacing CFC and HCFC compositions in refrigeration applications.

摘要:
A process for recovering waste heat which comprises (a) passing a liquid phase working fluid through a heat exchanger in communication with a process which produces the waste heat; (b) removing a vapour phase working fluid from the heat exchanger; (c) passing the vapour phase working fluid to an expander, wherein the waste heat is converted into mechanical energy; and (d) passing the vapour phase working fluid from the expander to a condenser, wherein the vapour phase working fluid is condensed to the liquid phase working fluid. The preferred working fluid is an organic Rankine cycle system working fluid comprising one or more compounds selected from the group consisting of 1,1,1,2,2,4,4,4-octafluorobutane, 2-trifluoromethyl-1,1,1,3,3-pentafluoropropane, 1,1,1,2,2,3,3,4-octaflourobutane, 1,1,1,2,2,3,3,4,4-nonafluorobutane, trifluoromethyl-1,1,1,2,2,-pentaflouropropyl ether or 3-trifluoromethoxy - 1,1,1,2,2-pentafluoropropane, 1,1,1-trifluoroethyl perfluoroethyl ether or 2-perfluoroethyl-1,1,1-trifluoroethane, 2-trifluoromethyl-1,1,1,3,3,3-hexafluoropropane or 2-H perfluoroisobutane, methyl (1,1,1,2,3,3,3-heptafluoropropane)-2-ether or 2-methoxy perfluoropropane, methyl 1,1,1,2,2,3,3-heptafluoropropane ether or 3-methoxyperfluoropropane, 1,2,2,2-Tetrafluoroethyl-1,1,1,2,2,3,3-heptafluoropropane ether or 2-perfluoropoxy-1,1,1,2-tetrafluoroethane, perfluoro-tertiary butyl alcohol, 1,1,2,2,3,3,4,4-octafluorobutane, 1,1,1,2,2,3,3,4,4,5,5-undecafluoropentane, 1,1,1,2,3,4,4,5,5,5-decafluoropentane, 4-trifluoromethyl-1,1,1,3,5,5,5-heptafluoro-2-pentene, cyclo-1,1,2,2,3,4,-hexafluorobutane, cyclo-1,1,2,2,3,3,4,4,5,5-decafluoropentane, and H-dodecafluoropentane isomers.
