Abstract

A process for the selective dehydrochlorination of a hydrochlorofluoroalkane by using chloride fluorides of Ba, Ca, or Sr as catalysts, wherein the hydrochlorofluoroalkane comprises a carbon atom or carbon atoms carrying at least one chlorine and at least one fluorine atom and further comprises at least one hydrogen atom on a carbon atom vicinal to the carbon atom or to the carbon atoms carrying the at least one chlorine and at least one fluorine atom.
