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.
本发明涉及一种改进的方法,通过在蒸汽相反应器中,在蒸汽相氟化催化剂和稳定剂的存在下,将1,1,2,3-四氯丙烯、1,1,1,2,3-五氯丙烷和/或2,3,3,3-四氯丙烯与氟化氢反应,制造2-氯-3,3,3-三氟丙烯(HCFC-1233xf)。HCFC-1233xf是生产2,3,3,3-四氟丙烯(HFO-1234yf)的中间体,后者是一种具有低全球变暖潜力的制冷剂。
