Abstract:
A new chromium-containing fluorination catalyst is described. The catalyst comprises an amount of zinc that promotes activity and from 0.1 to 8.0% by weight of the chromium in the catalyst based on the total weight of the chromium is present as chromium (VI). The use of the zinc-promoted, chromium-containing catalyst in a fluorination process in which a hydrocarbon or halogenated hydrocarbon is reacted with hydrogen fluoride in the vapor-phase at elevated temperatures is also described.
