  Process for the manufacture of ketones

  摘要：

  酮类化合物是通过将羧酸卤化物，特别是羧酸氯化物，与铝烷基化合物反应制备的，可选地在三卤化铝的存在下，在甲基氯中作为溶剂，在大约20度至大约100度C之间的温度下进行，最好在大约30度至大约60度C之间，更好地在大约40度C左右进行，这是甲基氯的回流温度。在操作温度高于约40度C时，施加高于大气压的压力。反应混合物通常按惯例处理，适当地通过水解后进行蒸馏。

  Highly active 8-benzoxazolyl- or 8-benzothiazolyl-2-alkylquinolinylnickel(II) complexes for ethylene dimerization and vinyl polymerization of norbornene

  摘要：

  The series of nickel halide complexes LNiX2 (C1-C6, X = Cl; C7-C12, X = Br), where L represents one of 8-benzoxazolyl-2-alkylquinoline or 8-benzothiazolyl-2-alkylquinoline derivatives, have been prepared. The molecular structures of the representative complexes C1, C3, C6 and C11 were determined by single crystal X-ray diffraction. Upon activation with ethylaluminium sesquichloride (EASC), all nickel complex precatalysts exhibited good activities for ethylene dimerization. Furthermore, such nickel pre-catalysts, in the presence of methylaluminoxane (MAO), were capable of the vinyl polymerization norbornene. (C) 2012 Elsevier Ltd. All rights reserved.

  The invention relates to a process for preparing trialkylgallium compounds of the general formula R3Ga. The process is based on the reaction of gallium trichloride (GaCh), optionally in a mixture with partially alkylated products, with an alkylaluminium compound of the type RaAICIb (where R = C1-C5-alkyl, a = 1, 2 or 3, b = 0, 1 or 2 and a + b = 3) in the presence of at least two alkali metal halides (e.g. NaCI and KCI) as auxiliary base. Preference is given to using alkylaluminium sesquichloride (R3AI2CI3) or trialkylaluminium (R3AI). The reaction mixture is heated to a temperature in the range from 120°C to 250°C and the trialkylgallium compound formed is separated off via a separator which is operated at a temperature which is more than 30°C below the boiling point of the most volatile partially alkylated product. Complete alkylation is achieved here and partially alkylated products are recirculated to the reaction mixture. In a further step, the reaction mixture can be heated to a maximum of 350°C and the remaining fully alkylated and partially alkylated products can be separated off. The process provides a high yield of trialkylgallium compound and displays high gallium utilization; the products are used, e.g., as precursors for MOCVD processes.

  该发明涉及一种制备一般式为R3Ga的三烷基镓化合物的过程。该过程基于氯化镓（GaCl3）与一种类型为RaAlClb（其中R = C1-C5-烷基，a = 1、2或3，b = 0、1或2，a + b = 3）的烷基铝化合物反应，可选地与部分烷基化产物混合，同时在至少两种碱金属卤化物（例如NaCl和KCl）的辅助碱存在下进行。优选使用烷基铝酮三氯化物（R3Al2Cl3）或三烷基铝（R3Al）。将反应混合物加热至120°C至250°C的温度范围，并通过在沸点最易挥发的部分烷基化产物的沸点以下30°C以上的温度下操作的分离器将生成的三烷基镓化合物分离出来。在这里实现了完全烷基化，部分烷基化产物被重新循环到反应混合物中。在进一步的步骤中，反应混合物可以加热至最高350°C，并且可以分离出剩余的完全烷基化和部分烷基化产物。该过程提供了高产率的三烷基镓化合物，并显示出高镓利用率；这些产物可用作MOCVD过程的前体。

  The invention relates to a process for preparing trialkylmetal compounds of the general formula R3M (where M = metal of group llIA of the Periodic Table of the Elements (PTE), preferably gallium or indium, and R = C1-C5-alkyl, preferably methyl or ethyl). The process is based on the reaction of metal trichloride (MeCl3) with alkylaluminium sesquichloride (R3AI2CI3) in the presence of at least one alkali metal halide as auxiliary base. The reaction mixture is heated to a temperature above 120°C and the trialkylmetal compound is separated off from the reaction mixture via a separator, with partially alkylated products being at the same time recirculated to the reaction mixture. In a further step, the reaction mixture is heated to a maximum of 350°C and the remaining alkylated and partially alkylated products are separated off. The products obtained in this way can optionally be recycled in the process. The process displays a high yield of trialkylmetal compound and also a high metal utilization; the products are used as precursors for MOCVD processes.

  该发明涉及一种制备三烷基金属化合物的方法，其通式为R3M（其中M为元素周期表（PTE）中IIIA族金属，优选为镓或铟，R为C1-C5烷基，优选为甲基或乙基）。该方法基于金属三氯化物（MeCl3）与烷基铝三氯化物（R3AI2CI3）在至少一种碱金属卤化物辅助碱的存在下反应。反应混合物加热至120°C以上的温度，通过分离器从反应混合物中分离出三烷基金属化合物，同时部分烷基化产物同时回流到反应混合物中。在进一步的步骤中，将反应混合物加热至最高350°C，并分离出剩余的烷基化和部分烷基化产物。以这种方式获得的产品可以选择性地在过程中回收利用。该方法显示出高产率的三烷基金属化合物和高金属利用率；这些产品被用作金属有机化学气相沉积（MOCVD）过程的前体。
