１，１，１，３，３−ペンタフルオロプロパン、トランス−１−クロロ−３，３，３−トリフルオロプロペン、及びトランス−１，３，３，３−テトラフルオロプロペンを共製造するための統合方法
Document Type and Number:
Japanese Patent JP2014525893
Kind Code:
A
Abstract:
Disclosed is a fully integrated process for making 1,1,1,3,3-pentafluoropropane (HFC-245fa), trans-1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)), and trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)). The chemistry involves (a) the reaction of 1,1,1,3,3-pentachloropropane (HCC-240fa), or a derivative thereof selected from 1,1,3,3-tetrachloropropene and 1,3,3,3-tetrachloropropene, with anhydrous HF in excess in the presence of a catalyst in a liquid-phase reactor in such a way as to co-produce HCFO-1233zd, HFO-1234ze, HCFC-244fa (3-chloro-1,1,1,3-tetrafluoropropane), and HFC-245fa in a first reactor; (b) the reaction of HCFO-1233zd and HFO-1234ze with HCl in excess in the presence of a catalyst in a second reactor to convert these two olefins into HCFC-243fa and HCFC-244fa, respectively; (c) the reaction of HCFC-243fa and HCFC-244fa over a dehydrochlorination catalyst or in a caustic solution in a third reactor to form HCFO-1233zd and HFO-1234ze; and (d) the reaction of HCFO-1233zd(Z) and HFO-1234ze(Z) in the presence of a catalyst in a fourth reactor to form trans-1233zd and trans-1234ze, respectively.
