The present invention provides a simple three step process for the production of 1,3,3,3-tetrafluoropropene (HFO-1234ze). In the first step, carbon tetrachloride is added to vinyl fluoride to afford the compound CCl
3
CH
2
CHClF (HCFC-241fb). HCFC-241fb is then fluorinated with anhydrous HF to afford CF
3
CH
2
CHClF (HCFC-244fa) in the second step. Dehydrochlorination of HCFC-244fa, in the third step, affords the desired product, CF
3
CH═CHF (HFO-1234ze). Following similar chemistry, vinyl chloride may be used in place of vinyl fluoride.
本发明提供了一种简单的三步过程,用于生产1,3,3,3-四
氟丙烯(
HFO-1234ze)。在第一步中,将
四氯化碳加入到
乙烯氟化物中,得到化合物CCl3CH2CHClF(HCFC-241fb)。然后,在第二步中,使用无
水氢氟酸对HCFC-241fb进行
氟化,得到CF3CH2CHClF(HCFC-244fa)。在第三步中,对HCFC-244fa进行脱氢
氯化,得到所需的产物CF3CH═CHF(
HFO-1234ze)。使用类似的
化学方法,可以用
氯乙烯代替
氟乙烯。
