    摘要: The present invention relates to an improved method for manufacturing 2-chloro-3,3,3,-trifluoropropene (HCFC-1233xf) by reacting 1,1,2,3-tetrachloropropene, 1,1,1,2,3-pentachloropropane, and/or 2,3,3,3-tetrachloropropene with hydrogen fluoride, in a vapor phase reaction vessel in the presence of a vapor phase fluorination catalyst and stabilizer. HCFC-1233xf is an intermediate in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf) which is a refrigerant with low global warming potential.

    摘要: The invention provides an improved process to manufacture 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) by reacting 2-chloro-3,3,3,-trifluoropropene (HCFO-1233xf) with hydrogen fluoride, in the presence of a fluorination catalyst, where by using 2-chloro-3,3,3,-trifluoropropene (HCFO-1233xf) of high purity, the need to add an oxidizing agent (typically chlorine) to keep the catalyst active can be avoided. The HCFC-244bb is then used as an intermediate in the production of 2,3,3,3-tetrafluoropropene-1 (HFO-1234yf).
