摘要： A tetraalkylthiuram disulfide is prepared in a higher yield without formation of by-products by subjecting the corresponding alkali metal dialkyldithiocarbamate to electrolytic oxidation, which is carried out in a two-layer electrolytic solution consisting essentially of either (1) water and carbon disulfide or (2) water and a mixture of carbon disulfide and a halogenated alkane of higher density than water, the carbon disulfide being predominant in the mixture, by means of electrodes placed in the aqueous layer containing the dialkyldithiocarbamate. The resulting disulfide is extracted to the lower layer of the electrolytic solution and is recovered from the layer. The dialkyldithiodicarbamate can be continuously produced in situ by adding carbon disulfide and dialkylamine gradually to the aqueous layer of the electrolytic solution, which contains an alkalimetal hydroxide produced during the electrolytic oxidation of the dialkyldithiocarbamate.
摘要翻译：通过使相应的二烷基二硫代氨基甲酸碱金属二烷基二硫代氨基甲酸盐进行电解氧化，可以以较高的产率制备四烷基秋兰姆二硫化物而不形成副产物，该电解氧化基本上由（1）水和二硫化碳组成的双层电解质溶液或（ 2）水和二硫化碳与卤化烷烃的混合物比水密度高，二硫化碳在混合物中占优势，借助放置在含二烷基二硫代氨基甲酸二烷基酯的水层中的电极。将得到的二硫化物萃取到电解液的下层，并从层中回收。二烷基二硫代氨基甲酸二烷基酯可以通过在二烷基二硫代氨基甲酸酯的电解氧化中产生的含有碱金属氢氧化物的电解液的水层中逐渐加入二硫化碳和二烷基胺而原位连续生产。
