  Disclosed is a hydrocarboxylation process for the production of carboxylic acid from olefins wherein an olefin, water, a Group VIII metal hydrocarboxylation catalyst, an onium salt compound are combined in a reaction zone and contacted with carbon monoxide under hydrocarboxylation conditions of pressure and temperature The process does not require or utilize the addition of a hydrogen halide or an alkyl halide exogenous or extraneous to the hydrocarboxylation process.

  揭示了一种从烯烃生产羧酸的羟基羧化过程，其中在反应区域中将烯烃、水、第VIII族金属羟基羧化催化剂和一个胞离子盐化合物结合，并在压力和温度的羟基羧化条件下与一氧化碳接触。该过程不需要或利用氢卤化物或烷基卤化物作为羟基羧化过程的外部添加物。

  Disclosed is a continuous process wherein carbon monoxide, a carbonylatable reactant, and a halide in the gas phase are contacted with a non-volatile catalyst solution comprising an ionic liquid and a Group VIII metal to produce a carbonylation product in the gas phase. The process is useful for the continuous preparation of acetic acid by the carbonylation of methanol.

  披露了一种连续过程，其中一种可与羰基化反应的反应物一氧化碳和气相中的卤化物与一种非挥发性催化剂溶液接触，该溶液包括一种离子液体和一种第VIII族金属，以在气相中产生羰基化产物。该过程可用于通过对甲醇进行羰基化来连续制备醋酸。
• Process for alpha,beta-dihydroxyalkenes and derivatives

  Disclosed is a process wherein a first olefin selected from certain &agr;,&bgr;-dihydroxyalkenes and 4-(alkenyl)ethylenecarbonates is reacted with a second olefin reactant to produce an olefin metathesis product. When the first olefin reactant is an optically enriched or enantiomerically pure &agr;,&bgr;-dihydroxyalkene, cross metathesis reactions produce products possessing the same optical purity. The &agr;,&bgr;-dihydroxyalkenes and the 4-(alkenyl)ethylene carbonates may be converted to hydrogenated products, and the 4-(alkenyl)ethylenecarbonates may be decarboxylated to provide the corresponding epoxides. The products of the disclosure may be used as monomers for the preparation of specialty polyesters and as intermediates in the manufacture pharmaceuticals and other chemicals.

  本发明涉及一种工艺，其中从某些α，β-双羟基烯烃和4-（烯基）乙烯基碳酸酯中选择第一烯烃与第二烯烃反应，产生烯烃交换产物。当第一烯烃反应物是光学富集或对映纯的α，β-双羟基烯烃时，交叉烯烃反应产生具有相同光学纯度的产物。α，β-双羟基烯烃和4-（烯基）乙烯基碳酸酯可以转化为氢化产物，4-（烯基）乙烯基碳酸酯可以脱羧以提供相应的环氧化物。本发明的产物可用作特种聚酯的单体，以及制造药品和其他化学品的中间体。
• CARBONYLATION PROCESS
  申请人：Zoeller Joseph Robert

  公开（公告）日：2007-12-20

  Disclosed is a carbonylation process for the production of carboxylic acids, carboxylic acid esters and/or carboxylic acid anhydrides wherein a carbonylation feedstock compound selected from one or more organic oxygenates such as alcohols, ethers, and esters is contacted with carbon monoxide in the presence of a carbonylation catalyst and one or more onium compounds. The carbonylation process differs from known carbonylation processes in that a halide compound such as a hydrogen halide, typically hydrogen iodide, and/or alkyl halide, typically methyl iodide, extraneous or exogenous to the carbonylation process is not fed or supplied separately to the process.

  本发明揭示了一种用于生产羧酸、羧酸酯和/或羧酸酐的羰基化过程，其中选择一种或多种有机氧化物，例如醇、醚和酯的羰基化进料化合物，在羰基化催化剂和一种或多种离子化合物的存在下与一氧化碳接触。该羰基化过程不同于已知的羰基化过程，因为卤化物化合物，例如氢卤化物（通常为氢碘酸）和/或烷基卤化物（通常为碘甲烷），不是外部或外源性地提供给该过程。
