摘要 综述了低GWP值替代品1,3,3,3-四氟丙烯(HFO-1234ze)的制备方法,认为由氯乙烯和四氯化碳调聚成1,1,1,3,3-五氯丙烷(HCC-240fa),而后由HCC-240fa制备中间产物1-氯-1,3,3,3四氟丙烷(HCFC-244fa)和1,1,1,3,3-五氟丙烷(HFC-245fa),最后由中间产物制备HFO-1234ze是一条较合理的工艺路线。 The preparation of the low GWP alternative 1,3,3,3-tetrafluoropropene(HFO-1234ze) is reviewed. An economic process is recommended that comprises three stages. A telomerization of CH2=CHCl and CCl4 into 1,1, 1,3,3-pentachloropropane(HCC-240fa) is conducted, followed the hydrofluorination of HCC-240fa into: 1-chloro- 3,3,3-tetrafluoropropane(HCFC-244fa) and 1,1,1,3,3-pentafluoropropane(HFC-245fa),then dehydroehlorination HCFC-244fa and dehydrofluorination of HFC-245fa into HFC-1234ze.
