Title: 1,1,2,2,3,3,4,4-OCTAFLUOROBUTANE COMPOSITIONS
Abstract:
Compositions of 1,1,2,2,3,3,4,4-octafluorobutane and a compound of the formula selected from the group consisting of a 4-6 carbon linear or a cyclic hydrofluorocarbon or fluorocarbon, a 3-5 carbon fluoroether, a fluorinated alcohol, perfluoro-n-methylmorpholine, and an ether are disclosed. These compositions, which may be azeotropic or azeotrope-like, may be used as refrigerants, in small turbine high speed compressors. They may also 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, displacement drying agents or as an anesthetic.
