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.
本发明提供了一种生产2,3,3,3-四氟丙烯的方法,包括脱氟氢化1,1,1,2,3-五氟丙烷的步骤,其中1,3,3,3-四氟丙烯和1,1,3,3,3-五氟丙烷与1,1,1,2,3-五氟丙烷一起供给到含有催化剂的反应器中,同时进行脱氟氢化反应和异构化反应。根据本发明的方法,通过有效利用脱氟氢化反应的副产物,可以高效生产2,3,3,3-四氟丙烯(HFO-1234yf)。
