ABSTRACT:
The present invention relates to the discovery of compositions which include fluoroethane, 2-fluoropropane or tert-butylfluoride. These compositions are useful as pure components or with at least one of tetrafluoroethane, difluoroethane, hexafluoropropane, a hydrocarbon or dimethylether.These compositions are useful as aerosol propellants, refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, refrigerants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.
