Abstract
A method of making chlorofluorohydrocarbons including, contacting, a fluorinated hydrocarbon reagent in the vapor phase, with hydrogen chloride (HCl). The reaction is conducted in the presence of an effective amount of a catalyst, at an elevated temperature sufficient to effect hydrochlorination to form a reaction mixture including a chlorofluorohydrocarbon.
