Abstract
The present disclosure provides a method for co-production of hydrofluorocarbons, which includes the steps of: preheating a mixture of chlorinated olefin and hydrogen fluoride; transferring the mixture to the top of a reactor; simultaneously introducing 1,1,1,2,3,3-hexafluoropropene and dichloromethane to the middle of the reactor for reaction; dividing the reactor into three to six sections; filling each section with a catalyst; obtaining reaction products at an outlet of the reactor; and separating the reaction products to obtain various hydrofluorocarbon products, respectively. The present disclosure has the advantages of a high yield, an optimal selectivity and a low energy consumption.
