Abstract
This invention discloses a method for co-production of 1-chloro-3,3,3-trifluoropropene, 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene. This method includes inputting the mixed gases of hydrogen fluoride and 1,1,1,3,3-pentachloropropane together with 1,1,2,3-tetrachloropropene into a first reactor for a reaction to obtain a reaction product; directly inputting the reaction product into a second reactor to perform a reaction in the presence of a catalyst; separating hydrogen chloride from the obtained product; obtaining 1-chloro-3,3,3-trifluoropropene, 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene respectively after water washing, alkaline washing, drying and rectifying. This invention has the advantages of flexible production, simple process, small investment, low energy consumption and high conversion rate.
