Research progress in high value application of 1,1,1,2,2-pentafluoropropane
This article reviews the recent progress of 1,1,1,2,2-pentafluoropropane(HFC-245 cb)as a refrigerant and a raw material for synthesizing high value-added chemicals.The current situation and development prospects of the two value applications are discussed.Due to its own marginal flammability and potential regulatory risks,HFC-245cb has limited use scenarios and quantities as a refrigerant.As a raw material for synthesizing high value-added chemicals,current research mainly focuses on preparation of 2,3,3,3-tetrafluoropeopene(HFO-1234yf)by dehydrofluorination of HFC-245cb.Developing efficient and environmentally friendly dehydrofluorination catalyst and expanding the conversion pathway of HFC-245cb are the future development directions.
