ABSTRACT:
This invention relates to compositions that include at least one fluoroether and at least one hydrofluorocarbon. Included in this invention are compositions of a cyclic or acyclic hydrofluoroether of the formula CaFbH2a+2−bOcwherein a=2 or 3 and 3≦b≦8 and c=1 or 2 and a hydrofluorocarbon of the formula CnFmH2n+2−mwherein 1≦n≦4 and 1≦m≦8. Such compositions may be used as refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, aerosol propellants, 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.
