摘要： A method for coproducing hydrofluorocarbons, the method involving preheating a mixture of a chlorinated alkene and hydrogen fluoride and then introducing the mixture into the top of a reactor, while also introducing 1,1,1,2,3,3-hexafluoropropylene and dichloromethane into the middle portion of the reactor for a reaction to obtain a reaction product at an outlet of the reactor, wherein the reactor is divided into three to six sections, each of which is filled with a catalyst; and separating the reaction product to obtain a plurality of hydrofluorocarbon products, respectively. The method has advantages such as a high yield, a good selectivity, and a low energy consumption.
