Catalysis dehydrofluorination of 1,1,1,2,3,3-hexafluoropropane (HFC-236ea) to obtain 2,3,3,3-tetrafluoropropene (HFO-1225ye) for the production of envrionmentally friendly refrigerant HFO-1234yf

Abstract

Surface-fluorinated chromium oxyfluoride catalysts were prepared using TFA(aq)-treatment of chromium oxide wet gel.\ The catalyst successfully dehydrofluorinated HFC-236ea to produce HFO-1225ye with the less deactivation.
