  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。

  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。
