摘要： A method for producing a hydrofluoroolefin is provided. The formation of by-products of an over-reduced product having hydrogen added to a material chlorofluoroolefin and an over-reduced product having not only chlorine atoms but also fluorine atoms in the chlorofluoroolefin replaced with hydrogen atoms is suppressed in the method. The method includes reacting a specific chlorofluoroolefin with hydrogen in the presence of a catalyst supported on a carrier to obtain the hydrofluoroolefin. The catalyst is a catalyst composed of an alloy containing at least one platinum group element of palladium and platinum, and at least one second element of copper, gold, lithium, potassium, silver, zinc, tin, lead, and bismuth.

摘要： The present application provides a hydrodefluorodimerization process, which is useful in the synthesis of, for example, fluoroölefins that can be used as refrigerants, blowers and the like. The process is an “early-stage fluorination” process, wherein precursors containing fluorine are assembled into the desired product using a zerovalent nickel catalyst. Also provided is a liquid composition comprising one or more fluoroölefin produced by this catalytic process.

摘要： Disclosed is a process for the preparation of cis-1,1,1,4,4,4-hexafluoro-2-butene comprising contacting 1,1,1-trifluorotrichloroethane with hydrogen in the presence of a catalyst comprising ruthenium to produce a product mixture comprising 1316mxx, recovering said 1316mxx as a mixture of Z- and E-isomers, contacting said 1316mxx with hydrogen, in the presence of a catalyst selected from the group consisting of copper on carbon, nickel on carbon, copper and nickel on carbon and copper and palladium on carbon, to produce a second product mixture, comprising E- or Z-CFC-1326mxz, and subjecting said second product mixture to a separation step to provide E- or Z-1326mxz. The E- or Z-1326mxz can be dehydrochlorinated in an aqueous basic solution with an alkali metal hydroxide in the presence of a phase transfer catalyst to produce hexafluoro-2-butyne, which can then be selectively hydrogenated to produce Z-1, 1,1,4,4,4-hexafluoro-2-butene using using either Lindlar's catalyst, or a palladium catalyst further comprising a lantanide element or silver.
