PROCESS FOR 1,3,3,3-TETRAFLUOROPROPENE |
摘要 |
<p>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 CCl3CH2CHClF (HCFC-241fb). HCFC-241fb is then fluorinated with anhydrous HF to afford CF3CH2CHClF (HCFC-244fa) in the second step. Dehydrochlorination of HCFC-244fa, in the third step, affords the desired product, CF3CH=CHF (HFO-1234ze). Following similar chemistry, vinyl chloride may be used in place of vinyl fluoride.</p> |
