REFRIGERANTS BASED ON HYDROFLUOROETHER OF FLUOROETHER

摘要

Compositions comprising a hydrofluoroether or fluoroether of the formula CaFbH2a+2-bOc wherein a = 3 to 6, b = 1 to 14 and c = 1 or 2; an acyclic hydrofluorocarbon or fluorocarbon of the formula CdFeH2d+2-e wherein d = 4 to 6 and e = 1 to 14; a cyclic hydrofluorocarbon or fluorocarbon of the formula CmFnH2m-n wherein m = 4 to 6 and n = 1 to 12; a fluoroalcohol of the formula CrFsH2r+1-sOH wherein r = 4 to 6 and s = 1 to 13; or perfluoro-n-methylmorpholine wherein said compositions are useful as refrigerants, cleaning agents, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, expansion agents for polymers such as polyolefins and polyurethanes, and as power cycle working fluids are described.
