ABSTRACT:
The invention includes compositions of 1,2,2,3,3,4,4,4-octafluorobutane and bis(fluoromethyl) ether, 2,2,4,4-tetrafluorooxetane, 2,2,3,3-tetrafluorooxetane, 1-difluoromethoxy-1,1,2,2-tetrafluoroethane, 1-difluoromethoxy-1,2,2,2-tetrafluoroethane, 2,2,3,3,4,5,5-heptafluorotetrahydrofuran or 2,2,3,3,4,4,5-heptafluorotetrahydrofuran; 1,1,1,2,3,4,4,4-octafluorobutane and bis(fluoromethyl) ether, 2,2,4,4-tetrafluorooxetane, 2,2,3,3-tetrafluorooxetane, 1-difluoromethoxy-1,1,2,2-tetrafluoroethane, 1-difluoromethoxy-1,2,2,2-tetrafluoroethane, 2,2,3,3,4,5,5-heptafluorotetrahydrofuran, or 2,2,3,3,4,4,5-heptafluorotetrahydrofuran; 1,1,1,2,2,4,4,4-octafluorobutane and bis(fluoromethyl) ether, 2,2,4,4-tetrafluorooxetane or 2,2,3,3-tetrafluorooxetane; or 1,1,2,2,3,3,4,4-octafluorobutane and methyl tert-butyl ether, bis(fluoromethyl) ether or 1,1,1,2,2,3,3-heptafluoro-3-(1,2,2,2-tetrafluoroethoxy)propane. These compositions, which may be azeotropic or azeotrope-like, may be used as refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, aerosol propellants, refrigerants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents or displacement drying agents.
