    摘要： A process for producing a fluoroolefin of the formula: CF3CY═CXnHp wherein Y is a hydrogen atom or a halogen atom (i.e., fluorine, chlorine, bromine or iodine); X is a hydrogen atom or a halogen atom (i.e., fluorine, chlorine, bromine or iodine); n and p are integers independently equal to 0, 1 or 2, provided that (n+p)=2; comprising contacting, in the presence of a phase transfer catalyst, a compound of the formula: CF3C(R1aR2b)C(R3cR4d), wherein R1, R2, R3, and R4 are independently a hydrogen atom or a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, provided that at least one of R1, R2, R3, and R4 is halogen and there is at least one hydrogen and one halogen on adjacent carbon atoms; a and b are independently=0, 1 or 2 and (a+b)=2; and c and d are independently=0, 1, 2 or 3 and (c+d)=3; and at least one alkali metal hydroxide. The alkali metal hydroxide can be, for example, potassium or sodium hydroxide and the phase transfer catalyst can be, for example, at least one: crown ether such as 18-crown-6 and 15-crown-5; or onium salt such as, quaternary phosphonium salt and quaternary ammonium salt. The olef in is useful, for example, as an intermediate for producing other industrial chemicals and as a monomer for producing oligomers and polymers.

    摘要： Disclosed is a process for making hexafluoro-2-butyne comprising the steps of: (a) providing a composition comprising CF3CX═CXCF3, where X=halogen; and (b) treating CF3CX═CXCF3 with a dehalogenation catalyst in the presence of a halogen acceptor compound Y, where Y is not hydrogen. The halogen acceptor compound Y is a material capable of being halogenated, preferably a compound having a multiple bond, such as an alkyne, alkene, allene, or carbon monoxide. Another suitable material capable of being halogenated is a cyclopropane. A catalyst effectively transfers halogen from CF3CX═CXCF3 to the halogen acceptor compound. Since Y is not hydrogen, the formation of CF3CX═CHCF3 is greatly reduced or eliminated.
