  • Use of fluorinated ketones in fire extinguishing compositions
    Patent number: 6630075
    Abstract: Fire extinguishing compositions and methods for extinguishing, controlling, or preventing fires are described wherein the extinguishing agent is a fluorinated ketone having up to two hydrogen atoms, alone, or in admixture with a co-extinguishing agent selected from hydrofluorocarbons, hydrochlorofluorocarbons, perfluorocarbons, perfluoropolyethers, hydrofluoroethers, hydrofluoropolyethers, chlorofluorocarbons, bromofluorocarbons, bromochlorofluorocarbons, iodofluorocarbons, hydrobromofluorocarbons, and mixtures thereof.
    Type: Grant

  • Use of perfluoroketones as vapor reactor cleaning, etching, and doping gases
    Patent number: 6540930
    Abstract: Methods of using reactive gases containing a perfluoroketone having 4 to 7 carbon atoms for removing unwanted deposits that build up in a vapor reactor, for etching dielectric and metallic materials in a vapor reactor, and for doping a material in a vapor reactor are described. The perfluoroketones perform as well as or better than the standard perfluorocarbons used in the semiconductor industry but have minimal impact on global warming.

  • Preparation and reactions of omega-halosulfonyl perfluoroalkanesulfonates
    Patent number: 5011983
    Abstract: Omega-chlorosulfonyl perfluoroalkanesulfonates and omega-fluorosulfonyl perfluoroalkane sulfonates. These compounds can be used to prepare esters, amides, or latent catalysts for the polymerization of cationically-sensitive monomers. The .omega.-chlorosulfonyl perfluoroalkanesulfonates can be reacted with ethylenically unsaturated compounds to incorporate hydrophilic perfluoroalkanesulfonate groups into the ethylenically unsaturated compound.
