摘要: 由于零臭氧层破坏潜值和较低的温室效应值,2,3,3,3-四氟丙烯作为1,1,1,2-四氟乙烷的替代物,被认为是理想、高效、环保和最具潜力的第四代新型制冷剂,并已受到汽车空调行业的广泛关注。首先,本文介绍了含卤素丙烯烃的命名规则、四氟丙烯的物化特性和制冷性能;其次,简述了铬基催化剂的制备方法,分析了以1,1,2,3-四氯丙烯为原料经2-氯-3,3,3-三氟丙烯中间体,气相催化氟化合成四氟丙烯的反应条件和反应路径等的研究进展;最后简要探讨了氟氯交换反应的机理。铬基催化剂作为气相氟氯交换反应的主体催化剂,所具有的某些特殊性能是其他许多催化剂难以比拟的,但是铬的化合物有毒,建议开发具有高活性和稳定性的无毒非铬基催化剂。

Abstract: 2,3,3,3-tetrafluoropropene (HFO-1234yf), as a promising replacement for 1,1,1,2-tetrafluoroethane (HFC-134a), is considered as a new generation refrigerant in automotive air condition system due to its zero ozone depletion potential (ODP) value, a low global warming potential (GWP) value of 4 and excellent refrigerating ability.So HFO-1234yf has been widely concerned in automotive air conditioning industry.To date, a large number of patents were applied for synthetic methods for HFO-1234yf.In those patents, one of the effective routes to synthesize HFC-1234yf is that 1,1,2,3-tetrachloropropene (HCFO1230xa) is fluorinated to synthesis HFC-1234yf via intermediate 2-chloro-3,3,3-trifluoropropene (HCFC-1233xf) in the presence of a fluorination Cr-based catalysts.The purpose of this review article is to provide readers with nomenclature rules of fluorinated propene isomers, physicochemical properties, refrigerant's performance of HFO-1234yf and reaction conditions as depicted in the patent and open literature.Emphasis has been placed on catalysts preparation and reaction pathways, which aim at studying Cl/F exchange reaction mechanism.Combining with the urgently need of ODS substitutes technology, preparation of catalytic materials with high catalytic activities and long life-time and non-cr-based catalysts will become research topic.

Key words: 2,3,3,3-tetrafluoropropene chemical reaction greenhouse gas catalysis, 1,1,2,3-tetrachloropropene 2-chloro-3,3,3-trifluoropropene
