摘要
本文建立一种阴极间接电氧化体系 ,以WO52 -/WO4 2 -催化阴极还原生成的H2 O2 ,间接氧化二甲基亚砜 (DMSO) ,得到产品二甲基砜 :阴极间接电氧化体系具有重要的理论意义和普遍的应用价值 .本文研究了各种因素对生成二甲基砜电流效率的影响 ,获得了最佳工艺条件 ,电流效率大于 70 % ,母液可循环使用无污染 .
A cathodic indirect electro_oxidation system was established for indirect electro_oxidize dimethyl sulfoxide to dimethyl sulfone with electro_reduction generated H 2O 2 catalyzed by the pertungstate/tungstate(WO 5 2- /WO 4 2- )redox mediator. Influences of current density,pH,temperature,and the current efficiencies etc. on the cathodic indirect electro_oxidation of dimethyl sulfone were investigated for determining optimum reaction conditions.The current efficiency reached more than 70%.Mother_liquid could be recycled to use without pollution.
