Title:
METHOD OF MAKING HYDROFLUOROCARBONS AND HYDROCHLOROFLUOROCARBONS
Document Type and Number:
WIPO Patent Application WO2002055459
Kind Code:
A3
Abstract:
A method of producing hydrofluorocarbons and/or hydrochlorofluorocarbons by using halogenated alkanes as a principal reactant. Generally, the method comprises the step of: (a) reacting a starting halogenated alkane corresponding to the formula (I): H3C-CX3 wherein X is independently fluorine or chlorine, with a hydrohalocarbon adduct in the presence of a catalyst to form a hydrofluorocarbon and/or hydrochlorofluorocarbon.
