摘　　要：三氟乙烯(HFO-1123、TrFE)作为新型HFOs类制冷剂,其消耗臭氧潜能值(ODP)为0,百年全球变暖潜能值(GWP_(100))值仅为0.005,对环境友好且应用领域广泛,受到了世界各国广泛关注。其中,通过1,1,1,2-四氟乙烷(HFC-134a)催化裂解生成HFO-1123,不仅能够降低HFC-134a引起的温室效应,同时还能解决其产能过剩问题。总结了近年来HFC-134a脱氟化氢制备HFO-1123的国内外研究进展,对催化剂种类、制备方法、稀释气等方面进行分类归纳、讨论、总结,以期为HFC-134a脱氟化氢制备HFO-1123反应的未来研究提供参考。1,1,2-Trifluoroethylene(HFO-1123,TrFE),as a novel hydrofluoroolefin(HFO)refrigerant,possesses an Ozone Depletion Potential(ODP)of zero and a 100-year Global Warming Potential(GWP 100)value of merely 0.005,rendering it environmentally benign and suitable for diverse applications.This attribute has garnered substantial attention from scholars and experts worldwide.Notably,the catalytic cleavage of 1,1,1,2-tetrafluoroethane(HFC-134a)to yield HFO-1123 not only mitigates the greenhouse impact associated with HFC-134a,but also addresses the issue of its surplus production capacity.This article systematically reviews recent domestic and international advancements in the research on the dehydrofluorination of HFC-134a to synthesize HFO-1123,encompassing the categorization,discussion,and summarization of catalyst types,preparation methods,and diluent gases.The aim is to provide a comprehensive reference for future investigations into the dehydrofluorination of HFC-134a for the production of HFO-1123.
