【摘要】 随着《〈蒙特利尔议定书〉基加利修正案》政策的推动，对特定氟化物的管控和环保的要求日益严格，第四代制冷剂因其较低的全球变暖潜能值和零臭氧消耗潜能值的特性，正在逐渐取代第三代制冷剂，成为制冷剂领域中兼具优异性能与环保性的最优选择。综述了第四代氢氟烯烃制冷剂的最新制备进展，特别对1-氯-3,3,3-三氟丙烯、1,3,3,3-四氟丙烯和2,3,3,3-四氟丙烯的制备研究进行了阐述。针对第四代制冷剂的制备工艺改进、催化剂的选择与优化提出了建设性意见，并指出了未来研究方向。更多还原

【Abstract】 With the “Kigali Amendment to the Montreal Protocol” and the stricter environmental regulations on specific fluorides. The third-generation refrigerant are gradually replaced by fourth-generation refrigerant, that because fourth-generation refrigerant with lower global warming potential and zero ozone depletion potential. Fourth-generation refrigerant have become the optimal choice in the refrigerant field, with excellent performance and environmental friendliness. This paper analyses latest progress in making fourth-generation hydrofluoroolefin refrigerants, especially discussion on how to make 1-chloro-3,3,3-trifluoropropane, 1,3,3,3-tetrafluoropropane, and 2,3,3,3-tetrafluoropropane. This paper also gives advices on improving the preparation of fourth-generation refrigerants, choosing and optimizing catalysts, and points out future research directions.更多还原
