Abstract
The present invention provides a process for producing 2,3,3,3-tetrafluoropropene including the step of dehydrofluorinating 1,1,1,2,3-pentafluoropropane, wherein 1,3,3,3-tetrafluoropropene and 1,1,3,3,3-pentafluoropropane are supplied together with 1,1,1,2,3-pentafluoropropane to a reactor containing a catalyst to simultaneously perform dehydrofluorination reaction and isomerization reaction.According to the process of the present invention, 2,3,3,3-tetrafluoropropene (HFO-1234yf) can be efficiently produced by effectively using the by-products of the dehydrofluorination reaction.
