  • Chemoselective halogenation of 2-hydroperfluoroalkyl aldehydes
    作者:Donald A. Wiebe、Donald J. Burton
    DOI:10.1016/j.jfluchem.2012.03.013
    日期:2012.7
    2-Hydroaldehydes, RfCH(R)CHO, where Rf = CF3, C2F5, n-C3F7 and R = CF3, C2F5, n-C3F7, Ph, H, were prepared via acid hydrolysis of the corresponding vinyl ethers, RfC(R) = CHOCH3, which can be readily prepared by reaction of [Ph3P+C¯HOCH3] with the corresponding ketone. The 2-hydroaldehydes can be chemoselectively converted to the acyl halide, RfCH(R)C(O)X (X = Cl, Br), via free-radical halogenation
    2-羟基醛,R f CH(R)CHO,其中R f  = CF 3,C 2 F 5,n -C 3 F 7和R = CF 3,C 2 F 5,n -C 3 F 7,Ph, H,制备通过相应的乙烯基醚的酸水解,R ˚F C(R)= CHOCH 3,其可通过的反应容易地制备[博士3P+C¯霍奇3]与相应的酮。可以通过自由基卤化将2-氢醛化学选择性转化为酰基卤R f CH(R)C(O)X(X = Cl,Br)。全氟烷基使2-位失活,成为2-氢的自由基夺取基团,卤化仅发生在甲酰基氢上。但是,冰乙酸中的2-氢醛的卤代化学选择性地产生了2-卤醛,R f CX(CHO)CHO,X = Cl,Br。2-氢全氟酰基卤的水解提供了有用的途径来获得2-氢全氟烷基支链的羧酸,有用的乙烯酮前体。该途径避免了使用有毒的氟代烯烃,例如全氟异丁烯。

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.

    A process is disclosed for the separation of a mixture of HF and CF3CClFCF3. The process involves placing the mixture in a separation zone at a temperature of from about −30° C. to about 100° C. and at a pressure sufficient to maintain the mixture in the liquid phase, whereby an organic-enriched phase comprising less than 50 mole percent HF is formed as the bottom layer and an HF-enriched phase comprising more than 90 mole percent HF is formed as the top layer. The organic-enriched phase can be withdrawn from the bottom of the separation zone and subjected to distillation in a distillation column to recover essentially pure CF3CClFCF3. The distillate comprising HF and CF3CClFCF3 can be removed from the top of the distillation column while essentially pure CF3CClFCF3 can be recovered from the bottom of the distillation column. The HF-enriched phase can be withdrawn from the top of the separation zone and subjected to distillation in a distillation column. The distillate comprising HF and CF3CClFCF3 can be removed from the top of the distillation column while essentially pure HF can be recovered from the bottom of the distillation column. If desired, the two distillates can be recycled to the separation zone. Also disclosed are compositions of hydrogen fluoride in combination with an effective amount of CF3CClFCF3 to form an azeotrope or azeotrope-like composition with hydrogen fluoride. Included are compositions containing from about 38.4 to 47.9 mole percent CF3CClFCF3. Also disclosed are processes for producing 1,1,1,2,3,3,3-heptafluoro-propane. One process uses a mixture comprising HF and CF3CClFCF3 and is characterized by preparing essentially pure CF3CClFCF3 as indicated above, and reacting the CF3CClFCF3 with hydrogen. Another process uses an azeotropic composition as described above, and reacts the CF3CClFCF3 with hydrogen in the presence of HF. Also disclosed is a process for producing hexafluoropropene. This process is characterized by preparing essentially pure CF3CClFCF3 as indicated above, and dehalogenating the CF3CClFCF3.
