  • Publication number: 20130060069
    Abstract: A method for producing a tetrafluoroolefin, such as 2,3,3,3-tetrafluoropropene (HFO-123434), comprises dehydrofluorinating a pentafluoroalkane in a gas phase in the presence of a catalyst comprising chromium oxyfluoride. In a preferred embodiment, 2,3,3,3-tetrafluoropropene (HFO-1234yf) is produced by forming a catalyst comprising chromium oxyfluoride by calcining CrF3?xH2O, where x is 1-10, in the presence of a flowing gas comprising nitrogen to form a calcined chromium oxyfluoride, and dehydrofluorinating 1,1,1,2,2-pentafluoropropane (HFC-245cb) in a gas phase in the presence of the catalyst to form the 2,3,3,3-tetrafluoropropene (HFO-1234yf).

  • Patent number: 8388857
    Abstract: Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrfluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.

  • Publication number: 20130041048
    Abstract: The present invention is directed towards a method of stabilizing thermosetting foam blends such as polyurethane poly blends containing a blowing agent with negligible (low or zero) ozone-depletion and low GWP based upon unsaturated halogenated hydroolefins in which one or more ester is added to the thermosetting foam blends. The thermosetting foam blends typically in clued: polyol(s); surfactant(s); catalyst(s); flame retardent(s); organic acid inhibitor(s)/stabilizer(s); carbon dioxide generating agent(s). The addition of the one or more esters to the thermosetting foam blends was unexpectedly found to result in blends which were stable over time and the resulted foams have a uniform cell structure with little or no foam collapse.

  • Publication number: 20130035526
    Abstract: A method for producing a tetrafluoroolefin, such as 2,3,3,3-tetrafluoropropene (HFO-1234yf), comprises contacting 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb) with or without a catalyst under conditions effective to convert the 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb) to the tetrafluoroolefin, optionally, via an intermediate. The conversion may be a one-step fluorination or a two-step fluorination and dehydrochlorination process. The 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb) may also be obtained by dehydrochlorinating 1,2,3-trichloropropane (HCC-260da) to form 2,3-dichloropropene (HCO-1250xf); fluorinating 2,3-dichloropropene (HCO-1250xf) to form 1,2-dichloro-2-fluoropropane (HCFC-261bb); and chlorinating 1,2-dichloro-2-fluoropropane (HCFC-261bb) to form 1,1,1,2-tetrachloro-2-fluoropropane (HCFC-241bb).
