    摘要: An alcohol such as methanol is reacted with carbon monoxide in a liquid reaction medium including a catalyst, an alkyl iodide such as methyl iodide, alkyl acetate such as methyl acetate in specified proportions, an additive, and an effective amount of water, where the additive increases an ionic character of the hydrogen iodide bond and the effective amount of water is sufficient to facilitate carboxylic acid release after carbonylation at the catalyst and to reduce anhydride formation. The present reaction system not only provides an acid product at water levels considerable below levels currently used, but also provides unexpected reaction rates and unexpected high catalyst stability.

    摘要: A process for the telomerization of a conjugated alkadiene with an organic hydroxy compound to produce an organo-oxyalkadiene is disclosed. A palladium catalyst having an ionic ligand is employed in a substantially oxygen-free environment in the presence of an aprotic polar solvent so that the reaction products may be separated from the catalyst by solvent extraction with a hydrocarbon solvent.

    摘要: A method is disclosed for the production of esters by reaction of an alkyl acyclic allylic ether such as 8-methoxy-1,6-octadiene with carbon monoxide in the presence of a halide of nickel, cobalt or iron as a catalyst and especially nickel iodide for the production of esters. Carbonylation of 8-methoxy-1,6-octadiene results in the production of methyl-3,8-nonadienoate; 2-(carbomethoxymethyl)-vinylcyclopentane; 2-(carbomethoxymethyl)-6-vinylcyclohexanone and 2-carbomethoxymethylbicyclo(3.3.0)-octan-3-one.

    摘要: A process for the telomerization of a conjugated alkadiene with an alkanol is disclosed for the production of an organo-oxyalkadiene. A palladium catalyst having a phosphine or stibene ligand is employed in a substantially oxygen-free environment and in the presence of a high boiling solvent so that the reaction products may be separated from the catalyst by distillation. Vacuum fractional distillation is a preferred method for separating the products.

    摘要: Disclosed is a method for removing aldehyde impurities from a methyl acetate supply. The method comprises reacting the methyl acetate supply with a polyol and converting the aldehyde impurities to cyclic acetals. The acetals are subsequently removed from the methyl acetate supply by, e.g., distillation. The purified methyl acetate supply is used for carbonylation to produce acetic acid.
