Abstract: The current invention relates to a process for making a tetrafluoropropene using a tetrafluorochloropropane and/or a pentafluoropropane as starting or intermediate reagents. More specifically, though not exclusively, the present invention relates to a novel method for preparing a tetrafluoropropene by dehydrohalogenating a starting or intermediate tetrafluorochloropropane and/or pentafluoropropane material in the presence of a caustic solution at a temperature range greater than 40° C. and less than or equal to 80° C.

Abstract: A method for preparing 2,3,3,3-tetrafluoroprop-1-ene comprising (a) providing a starting composition comprising at least one compound having a structure selected from Formulae I, II and III: CX2?CCl—CH2X??(Formula I) CX3—CCl?CH2??(Formula II) CX3—CHCl—CH2X??(Formula III) wherein X is independently selected from F, Cl, Br, and I, provided that at least one X is not fluorine; (b) contacting said starting composition with a first fluorinating agent to produce a first intermediate composition comprising 2-chloro-3,3,3-trifluoropropene and a first chlorine-containing byproduct; (c) contacting said first intermediate composition with a second fluorinating agent to produce a second intermediate composition comprising 2-chloro-1,1,1,2-tetrafluoropropane and a second chlorine-containing byproduct; and (d) catalytically dehydrochlorinating at least a portion of said 2-chloro-1,1,1,2-tetrafluoropropane to produce a reaction product comprising 2,3,3,3-tetrafluoroprop-1-ene.

Abstract: Disclosed is a process for the making chlorotrifluoroethylene. The process comprises the step of reacting 1,1,2-trichlorotrifluoroethane with a reducing metal in the presence of a polar aprotic solvent under conditions sufficient to form chlorotrifluoroethylene.

Abstract: Systems and processes relating to the formation and production of CFO-1113 HCFC-123a. Such systems and processes can include one or more reactors in series that react HCFC-123a and base to produce reaction product vapors including CFO-1113. Optionally, a phase transfer agent or catalyst can be added to the reaction to enhance the reaction rate. The CFO-1113 can be separated from the reaction product vapors to produce a CFO-1113 product stream. The reactions can be conducted continuously, and a liquid effluent stream can be removed from the reactors during the reaction. Unreacted HCFC-123a can be separated from the liquid effluent stream and provided back to the reactors.
