摘　　要：介绍了几种典型的C3氢氟烯烃(HFOs),叙述了氢氟化、脱氟化氢和加氢脱卤化法制备C3HFOs的方法及其特点,展望了C3HFOs的应用与发展。认为反应应以铬系催化剂为主,催化剂的选择尤其重要是高效获取目标产物的关键,碱金属掺杂有助于催化剂选择性的提高。Several typical C3 hydrofluoroolefins(HFOs)were introduced.The preparation methods and characteristics of C3 HFOs by hydrofluorination,dehydrofluorination and hydrodehalogenation were described.The application and development of C3 HFOs were prospected.It is believed that the reaction should be dominated by chromium-based catalysts.The selection of catalysts is particularly important to obtain the target product efficiently.Alkali metal doping is helpful to improve the selectivity of the catalyst.
