  • Methods for preparing ethers, ether compositions, fluoroether fire extinguishing systems, mixtures and methods
    Patent number: 6849194
    Abstract: Highly fluorinated, saturated, and unsaturated fluoroethers are efficient, economical, non-ozone-depleting fire extinguishing agents used alone or in blends with other fire extinguishing agents in total flooding and portable systems. Methods for producing ethers, halogenated ether intermediates, and fluoroethers are disclosed. Novel fluoroether compositions are disclosed. Fluoroether extinguishing mixtures, methods, and systems are disclosed.
    Type: Grant

  • Materials and methods for the conversion of hydrofluorocarbons
    Publication number: 20040127757
    Abstract: Methods and materials are disclosed for the recovery of valuable hydrofluorocarbons and subsequent conversion to environmentally inert compounds. More specifically methods and materials are provided for recovering hydrofluorocarbons such as HFC-227, HFC-236, HFC-245, HFC-125, HFC-134, HFC-143, HFC-152, HFC-32, HFC-23 and their respective isomers. Processes are provided for converting hydrofluorocarbons such as these to fluoromonomer precursors such as CFC-217, CFC-216, CFC-215, CFC-115, CFC-114, CFC-113, CFC-112, HCFC-22, CFC-12, CFC-13 and their respective isomers. Materials, methods and schemes are provided for the conversion of these fluoromonomer precursors to fluoromonomers such as HFP, PFP, TFP, TFE, and VDF.
