PROCESS FOR MAKING TETRAFLUOROPROPENE
The present invention describes a process for making CF3CH CHF (HFO-1234ze). The process involves the addition of carbon tetrachloride (CCl4) to 1,2-dichloroethylene to form CCl3CHClCHCl2. The compound CCl3CHClCHCl2 thus can then either be treated with HF to produce CF3CHClCHClF as the main product,...

description | The present invention describes a process for making CF3CH CHF (HFO-1234ze). The process involves the addition of carbon tetrachloride (CCl4) to 1,2-dichloroethylene to form CCl3CHClCHCl2. The compound CCl3CHClCHCl2 thus can then either be treated with HF to produce CF3CHClCHClF as the main product, or it can be converted to CCl2 CHCHCl2 (1230za) by dechlorination. CCl2 CHCHCl2 can be treated with HF such that the main product obtained is CF3CHClCHClF. CF3CH CHCl may be produced as a by-product, but upon treatment with HF, it affords the compound CF3CHClCHClF. The desired compound, CF3CH CHF (HFO-1234ze), is obtained as a trans/cis mixture by dehydrochlorination of CF3CH2CHClF or by dechlorination of CF3CHClCHClF. |
