Abstract
A method for concurrently producing different hydrofluoro carbons, comprising the reaction of halocarbon or hydrohalocarbon with hydrogen fluoride in a reaction system consisting of a series of at least two discrete reactors, in the presence of catalysts, said reactors each being provided with different reactant materials and differing in reaction conditions including the catalysts and/or reaction temperature, thereby flexibly controlling their production rates in accordance with fluctuations in their demand, and eliminating the risk of constructing large scale plants responsible for individual hydrofluorocarbons.
