摘要： To provide a method for producing a hydrofluoroolefin, wherein formation of an over-reduced product having hydrogen added to an aimed hydrofluorolefin and an over-reduced product having some of fluorine atoms in the aimed product replaced with hydrogen atoms, as by-products, is suppressed.A method for producing a hydrofluoroolefin, which comprises reacting a specific chlorofluoroolefin with hydrogen in the presence of a catalyst supported on a carrier, to obtain a specific hydrofluoroolefin, wherein the catalyst is a catalyst composed of particles of an alloy containing at least one platinum group metal selected from the group consisting of palladium and platinum, and gold, and the proportion of the gold at the surface of the alloy particles is from 5 to 30 mass % per 100 mass % in total of the platinum group metal and the gold at the surface of the alloy particles.

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.
