| abstract | The present invention describes a method for producing CF 3 CH═CHF (HFO-1234ze). The method includes adding carbon tetrachloride (CCl 4 ) to 1,2-dichloroethylene to form CCl 3 CHClCHCl 2 . The compound CCl 3 CHClCHCl 2 can then be treated with HF in this way to produce CF 3 CHClCHClF as the main product, or can be converted to CCl 2 ═CHCHCl 2 (1230za) by dechlorination. CCl 2 ═CHCHCl 2 can be treated with HF so that the main product obtained is CF 3 CHClCHClF. CF 3 CH═CHCl may occur as a by-product, but treatment with HF yields the compound CF 3 CHClCHClF. Desired compound CF 3 CH = CHF (HFO- 1234ze) as trans / cis mixture are obtained by CF 3 CH 2 CHClF dehydrochlorination or CF 3 CHClCHClF dechlorination. [Selection figure] None |
