Abstract: This invention relates to an improved method of producing a catalyst for the production of vinyl fluoride. This invention comprises incorporating activated carbon, which has been activated with nitric acid and subsequently washed so as to remove the acid with a mercuric compound or a cadmium compound, or a mixture of a mercuric compound and a compound consisting of chloride, fluoride, sulphate, nitrate, oxide or hydroxide of lead, tin, cadmium or zinc, and pre-treating the resultant material at a temperature of 30* to 300*C with hydrogen fluoride gas.

Abstract: THIS INVENTION RELATES TO AN IMPROVED CATALYST USABLE FOR PRODUCING VINYL FLUORIDE AND A METHOD OF PRODUCING VINYL FLUORIDE BY USING SUCH AN IMPROVED CATALYST. THE CATALYST IS COMPRISED OF A POROUS CARRIER WHICH IS IMPREGNATED WITH AT LEAST ONE MEMBER SELECTED FROM MERCURIC COMPOUNDS AND AT LEAST ONE MEMBER SELECTED FROM INORGANIC COMPOUNDS OF PB, SN, CD AND ZN. THE VINYL FLUORIDE IS PRODUCED BY THE REACTION OF ACETYLENE AND HYDROGEN FLUORIDE IN THE PRESENCE OF THE ABOVE CATALYST.
