本文以铅和汞齐为阴极,对马来酸电解还原为琥珀酸进行了研究,电解条件由极化曲线确定,在恒电位条件下,测定了反应物浓度、温度、电极材料和搅拌等因素对极限电流密度的影响.此外,对阳极用石棉和纤维复盖,现了无隔膜电化学合成,获得了较纯产品和较高的产率,并对还原机理进行了初步探讨. In this paper, lead and amalgam were used as cathodes to study the reduction of maleic acid to succinic acid. The electrolysis conditions were determined by the polarization curve. Under constant potential conditions, the reactant concentration, temperature, electrode material and stirring were measured On the limiting current density.In addition, the anode with asbestos and fiber covered, now no diaphragm electrochemical synthesis, to obtain a pure product and higher yield, and the reduction mechanism was discussed.
