    摘要: A process which can be used for producing thiolcarbamates is provided wherein the process comprises contacting a reaction mixture with a hydrocarbyl chloride such as, for example, benzyl chloride under a condition which is sufficient to produce a product mixture wherein the reaction mixture comprises carbonyl sulfide, an amine such as, for example, a secondary amine, a solvent; the solvent comprises a tertiary amine; and the reaction mixture, hydrocarbyl halide, and solvent are each present in an amount sufficient to effect the production of a thiolcarbamate. Optionally, the reaction mixture can also comprise a metal hydroxide. Further optionally, the product mixture can be contacted with a metal hydroxide if the reaction mixture does not comprise a metal hydroxide.

    摘要: A process for co-production of an alkenyl aromatic compound such as, for example, styrene and t-butylstyrene, and an oxygenated sulfur-containing compound such as, for example, a sulfoxide or a sulfone is disclosed which comprises: (1) contacting, in the presence or absence of a catalyst, an .alpha.-methyl benzylic hydroperoxide with an organic sulfide compound to produce a mixture of an .alpha.-methyl benzylic hydroxide and an oxygenated sulfur-containing compound; (2) separating the .alpha.-methyl benzylic hydroxide from the sulfur-containing compound; (3) contacting the .alpha.-methyl benzylic hydroxide with a base to convert the .alpha.-methyl benzylic hydroxide to the alkenyl aromatic compound; and optionally, (4) recovering the alkenyl aromatic compound from the oxygenated sulfur-containing compound. The sulfoxide produced can be oxidized to a sulfone. The contacting of the .alpha.-methyl benzylic hydroxide with a base can also be carried out before the .alpha.-methyl benzylic hydroxide is separated from the oxygenated sulfur-containing compound followed by separation of the sulfur-containing compound.

    摘要: A cobalt carbonyl phosphine complex useful for hydrogenation of cyclic polyenes to corresponding cyclic monoenes is prepared by reaction of dicobalt carbonyl and a phosphine compound in at least one non-oxygenated aliphatic solvent. Selective hydrogenation of the cyclic polyenes comprises an induction period during which the polyenes are contacted with the cobalt carbonyl complex catlayst under hydrogen pressure followed by decreasing the reaction temperature and pressure for a period of time sufficient to complete the hydrogenation.
