    Abstract: The present invention describes a process for making CF 3 CH=CHF (HFO-1234ze). The process involves the addition of carbon tetrachloride (CCl 4 ) to 1,2-dichloroethylene to form CCl 3 CHClCHCl 2 . The compound CCl 3 CHClCHCl 2 thus can then either be treated with HF to produce CF 3 CHClCHClF as the main product, or it can be converted to CCl 2 =CHCHCl 2 (1230za) by dechlorination. CCl 2 =CHCHCl 2 can be treated with HF such that the main product obtained is CF 3 CHClCHClF. CF 3 CH=CHCl may be produced as a by-product, but upon treatment with HF, it affords the compound CF 3 CHClCHClF. The desired compound, CF 3 CH=CHF (HFO-1234ze), is obtained as a trans/cis mixture by dehydrochlorination of CF 3 CH2CHClF or by dechlorination of CF 3 CHClCHClF.

    Abstract translation: 本发明描述了制备CF 3 CH = CHF(HFO-1234ze)的方法。 该方法包括向1,2-二氯乙烯中加入四氯化碳(CCl 4)以形成CCl 3 CHClCHCl 2。 因此,可以用HF处理化合物CCl 3 CHClCHCl 2以产生CF 3 CHClCHClF作为主要产物,或者可以通过脱氯将其转化为CCl 2 = CHCHCl 2(1230za)。 CCl 2 = CHCHCl 2可用HF处理,得到的主要产物为CF 3 CHClCHClF。 CF 3 CH = CHCl可以作为副产物来制备,但是在用HF处理时,得到化合物CF 3 CHClCHClF。 通过CF 3 CH 2 CHClF的脱氯化氢或通过CF 3 CHClCHClF的脱氯,获得期望的化合物CF 3 CH = CHF(HFO-1234ze),为反式/顺式混合物。
