    • 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.
    • 提供了可用于生产硫代氨基甲酸盐的方法,其中所述方法包括在足以产生产物混合物的条件下使反应混合物与烃基氯例如苄基氯接触,其中反应混合物包含硫化羰, 胺,例如仲胺,溶剂; 溶剂包括叔胺; 并且反应混合物,烃基卤化物和溶剂各自以足以产生硫代氨基甲酸盐的量存在。 任选地,反应混合物还可以包含金属氢氧化物。 进一步任选地,如果反应混合物不包含金属氢氧化物,则产物混合物可与金属氢氧化物接触。

    • 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.
    • 公开了一种共同制备链烯基芳族化合物如苯乙烯和叔丁基苯乙烯的方法和含氧化的含硫化合物,例如亚砜​​或砜,其包括:(1)接触 在存在或不存在催化剂的情况下,将α-甲基苄基氢过氧化物与有机硫化物混合以产生α-甲基苄基氢氧化物和含氧的含硫化合物的混合物; (2)从含硫化合物中分离α-甲基苄基氢氧化物; (3)使α-甲基苄基氢氧化物与碱反应以将α-甲基苄基氢氧化物转化为链烯基芳族化合物; 和(4)从含氧化合物中回收链烯基芳族化合物。 所生成的亚砜可以被氧化成砜。 α-甲基苄基氢氧化物与碱的接触也可以在将α-甲基苄基氢氧化物与含氧的含硫化合物分离,然后分离含硫化合物之前进行。
