  The present invention relates to new fluoroketone compounds from the groups monobromoperfluoroketones, monohydromonobromoperfluoroketones, (perfluoroalkoxy)monobromoperfluoroketones, (fluoroalkoxy)monobromoperfluoroketones, and monochloromonobromoperfluoroketones. These fluoroketone compounds have utility in preventing, controlling and extinguishing fire. These fluoroketone compounds have further utility as additives to reduce or eliminate the flammability of normally flammable working fluids such as refrigerants, foam blowing agents, solvents, aerosol propellants, and sterilants.

  本发明涉及来自单溴全氟酮、单氢单溴全氟酮、（全氟烷氧基）单溴全氟酮、（氟烷氧基）单溴全氟酮和单氯单溴全氟酮等组的新型氟酮化合物。这些氟酮化合物在预防、控制和扑灭火灾方面具有实用性。这些氟酮化合物还可作为添加剂，用于减少或消除通常易燃的工作流体（如制冷剂、发泡剂、溶剂、气溶胶推进剂和消毒剂）的可燃性。

  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.

  本发明涉及使用至少一种氟酮，所述氟酮从单溴全氟酮、单氢单溴全氟酮、（全氟烷氧基）单溴全氟酮、（氟烷氧基）单溴全氟酮和单氯单溴全氟酮中选择，用于：i）通过将该氟酮施加到火灾上来灭火；ii）通过将该氟酮引入含可燃物质的空气密闭区域中，并保持足够的氟酮量以抑制密闭区域内可燃物质的燃烧来防止火灾；以及iii）通过将约0.1至约99重量％的该氟酮与易燃工作流体混合来减少或消除易燃工作流体的易燃性。
