Advances on the gas-phase catalytic fluorination of 1 ,1 ,2,3-tetrachloropropene to 2,3,3,3-tetrafluoropropene
摘要
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.关键词
