摘　　要：含氟烯烃(HFOs)具有ODP为零、GWP值极低的优点,其中1,1,2-三氟乙烯(TrFE)可作为新能源汽车热泵工质、含氟高聚材料的合成单体、高附加值卤代烯烃制备的关键原料,有望实现在新能源汽车空调系统、压电材料与电卡制冷材料、高端芯片蚀刻等领域的广泛应用。本文对TrFE合成工艺进行分类,并详述各路线的技术难点与解决策略;针对主要合成路线即1,1,1,2-四氟乙烷(HFC-134a)脱氟化氢、1,1,2-三氯-1,2,2-三氟乙烷(CFC-113)催化加氢制备TrFE路线,对催化剂进行总结与归纳,讨论催化剂配方、制备方法、结构等因素对反应的影响。如何提高1,1,2-三氟乙烯选择性与催化剂稳定性是该研究的重点与难点,也是制约其产业化与商品化的决定因素。Hydrofluoroolefins(HFOs)have great potential in many applications due to their superior properties of zero ozone depletion potential(ODP)and low global warming potential(GWP).1,1,2-Trifluoroethene(TrFE),a novel HFO compound,is considered as a promising candidate of a heat pump working fluid in the air-conditioning system for the new energy vehicles or being used to synthesize the fluoropolymers which are further used as piezoelectric and electrocaloric cooling materials and to synthesize the high value-added alkenyl halides for microchips.In this review,we categorized the existing approaches for TrFE synthesis.The technical challenges of each method were elaborated and the potential solutions were discussed.For the most commonly used methods that use 1,1,1,2-tetrafluoroethane(HFC-134a)and 1,1,2-trichloro-1,2,2-trifluoroethane(CFC-113)as starting materials,the low selectivity to 1,1,2-trifluoroethene and the deactivation of the catalysts are the most critical challenges,which also limit the scaling-up and the commercialization of the technologies.
