  Kinetic and Mechanistic Studies for Reactions of CF₃CH₂CHF₂ (HFC-245fa) Initiated by H-Atom Abstraction Using Atomic Chlorine

  摘要：

  Kinetics and mechanisms of Cl atom initiated oxidation reactions of CF3CH2CHF2 (HFC-245fa) were investigated by long-path FTIR spectroscopic methods at 297 +/- 2 K. The Cl atoms initiated the reaction mainly via H-atom abstraction from the terminal carbon (greater than or equal to 95%) to produce a CF3CH2CF2 radical. Subsequent reactions in 700 Torr of air produced CF3CHO and CF2O as the primary products. Secondary reactions of CF3CHO with Cl atoms led to the formation of CF3C(O)OH, CF3OH, CO2, and CF3OOOCF3 in the experimental system. However, under atmospheric conditions, CF3CHO would undergo a series of rapid oxidation and decomposition reactions ultimately leading to HF and CO2, and no long-lived organic decomposition products would be produced.

  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 CH 2 CHClF or by dechlorination of CF 3 CHClCHClF.

  该发明描述了一种制备CF3CH═CHF（HFO-1234ze）的过程。该过程涉及将四氯化碳（CCl4）加入1,2-二氯乙烯以形成CCl3CHClCHCl2。然后，可以将该化合物CCl3CHClCHCl2与氢氟酸处理，产生CF3CHClCHClF作为主要产物，或者可以通过脱氯反应将其转化为CCl2═CHCHCl2（1230za）。CCl2═CHCHCl2可以与氢氟酸处理，主要产物为CF3CHClCHClF。CF3CH═CHCl可能作为副产物产生，但经过氢氟酸处理后，可以得到CF3CHClCHClF。所需的化合物CF3CH═CHF（HFO-1234ze）可通过脱氯反应CF3CH2CHClF或脱氯反应CF3CHClCHClF得到其顺反异构体混合物。

  A process is disclosed for the manufacture of CF3CH2CHF2 and CF3CHFCH2F. The process involves (a) reacting hydrogen fluoride, chlorine, and at least one halopropene of the formula CX3CCl=CClX (where each X is independently F or Cl) to produce a product including both CF3CCl2CClF2 and CF3CClFCCl2F; (b) reacting CF3CCl2CClF2 and CF3CClFCCl2F produced in (a) with hydrogen to produce a product including both CF3CH2CHF2, and CF3CHFCH2F; and (c) recovering CF3CH2CHF2 and CF3CHFCH2F from the product produced in (b). In (a), the CF3CCl2CClF2 and CF3CClFCCl2F are produced in the presence of a chlorofluorination catalyst including a ZnCr2O4/crystalline α-chromium oxide composition, a ZnCr2O4/crystalline α-chromium oxide composition which has been treated with a fluorinating agent, a zinc halide/α-chromium oxide composition and/or a zinc halide/α-chromium oxide composition which has been treated with a fluorinating agent.
