METHANE AND METHYL CHLORIDE AS SELECTIVE REDUCING AGENT IN THE TRANSFORMATION OF HYDROCHLOROFLUOROCARBONS OR CHLOROFLUORCARBONS TO HYDROCHLOROFLUOROCARBONS.

摘要

A gas phase reaction process for producing a hydrofluorocarbon from a hydrochlorofluorocarbon or chlorofluorocarbon reactant by contacting, in the presence of a catalyst, the hydrochlorofluorocarbon or chlorofluorocarbon reactant with a reducing agent selected from methane, methyl chloride and mixtures thereof, to produce the hydrofluorocarbon.
