Abstract

Fluorinated and/or fluorochlorinated aliphatic hydrocarbons are prepared by passing a chlorinated aliphatic hydrocarbon with gaseous hydrofluoric acid and, optionally, chlorine at a temperature of 100 DEG to 500 DEG C. over a catalyst containing thorium fluoride. An inert gas may also be present. The catalyst may be supported, e.g. on active carbon, and may be combined with aluminium and/or chromium fluoride and, optionally, with one or more oxides or basic fluorides of aluminium, chromium or thorium. Examples are given.ALSO:A catalyst for the fluorination of chlorinated aliphatic hydrocarbons (see Division C2) comprises thorium fluoride which may be supported on an inert support such as active carbon or may be combined with fluorides of aluminium or chromium and/or one or more oxides or basic fluorides of metals such as chromium, aluminium and thorium. Various methods of preparation are described. The catalyst may be re-activated by heating at a temperature below 600 DEG C. in a light current of air or at a temperature below 800 DEG C. in a current of air and steam.
