Progress on the synthesis of 2,3,3,3-tetrafluoropropene and the catalysts
摘要
Abstract
2,3,3,3-tetrafluoropropene(HFO-1234yf)offers the advantages of zero ozone depletion potential(ODP)and low global warming potential(GWP).Its thermophysical properties closely resemble those of the third-generation refrigerant 1,1,1,2-Tetrafluoroethane(HFC-134a),enabling HFO-1234yf to serve as a direct replace-ment for HFC-134a in existing automotive air conditioning systems without necessitating any design modifications.HFO-1234yf has become one of the most promising candidates among fourth-generation heat transfer fluids.This paper provides a comprehensive review of the current synthesis routes for HFO-1234yf,comparing the advantages and limitations of each approach.It proposes that the synthesis of HFO-1234yf from C2 feedstocks,such as 2-chloro-1,1-difluoroethylene,or from C3 feedstocks,such as 1,1,1,2,2,3-hexachloropropane and 3,3,3-triflu-oropropene,offers several benefits,including high yields,the ready availability of raw materials,and mild reaction conditions,which collectively enhance the process's value for industrial applications.The catalysts employed in key reactions such as telomerization,hydrogenation,fluorination,and dehydrohalogenation within the synthesis routes of HFO-1234yf are also summarized.Finally,the paper emphasizes future research directions,suggesting that priorities should focus on developing new,green,and efficient synthesis routes.Additionally,it advocates for the design of long lifetime telomerization catalysts that offer high conversion rates and selectivity,ease of regenera-tion,and the development of highly active,durable,and carbon-resistant non-chromium-based catalysts to replace environmentally harmful chromium-based catalysts.关键词
