    摘要： The present invention relates to methods of using at least one fluoroketone selected from monobromoperfluoroketones, monohydromonobromoperfluoroketones, (perfluoroalkoxy)monobromoperfluoroketones, (fluoroalkoxy)monobromoperfluoroketones, and monochloromonobromoperfluoroketones for i) extinguishing fire by applying to the fire such a fluoroketone, ii) preventing fire in an air-containing enclosed area containing combustible materials by introducing into the area such a fluoroketone and maintaining the fluoroketone in an amount sufficient to suppress combustion of combustible materials in the enclosed area, and iii) reducing or eliminating the flammability of a flammable working fluid, by mixing between about 0.1 to about 99 percent by weight of such a fluoroketone with the flammable working fluid.

    摘要： A process for the preparation of pentafluoroethane is disclosed which involves contacting a mixture comprising hydrogen fluoride and at least one starting material selected from haloethanes of the formula CX3CHX2 and haloethanes of the formula CX2═CX2, where each X is independently selected from the group consisting of F and Cl (provided that no more than four of X are F), with a fluorination catalyst in a reaction zone to produce a product mixture comprising HF, HCl, pentafluoroethane, underfluorinated halogenated hydrocarbon intermediates and less than 0.2 mole percent chloropentafluoroethane based on the total moles of halogenated hydrocarbons in the product mixture. The process is characterized by the fluorination catalyst comprising (i) a crystalline cobalt-substituted alpha-chromium oxide where from about 0.05 atom % to about 6 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by trivalent cobalt (Co+3) and/or (ii) a fluorinated crystalline oxide of (i).
