【摘要】 研究了在碱性介质中汞电极上电还原单糖、二糖得到相应的多元醇。实验结果表明，电极过程由在汞表面吸附糖的电子转移及动力学混合控制。但电位电解的结果显示，其电解选择性为１００％，对乳糖、葡萄糖及果糖的电流效率分别为６０％、７４％及８０％，其电解产物为相应的多元醇。并报道了二糖的电还原研究结果，提出了糖类电还原机理。更多还原

【Abstract】 A polarographic investigation of direct electroreduction disaccharide and monosaccharide onDME to corresponding polyalcohols in alkaline acquous media is described. The experimental results show thatthe electrode process is controlled by the mixture control of charge transfer and kinetical steps with theadsorption of sugar to the surface of mercury electrode. A practically 100% yield in corresponding polyalcoholsand 60%, 74% and 83% yield in current for lactose, glucose and fructose respectively are realized. Specially, theinvestigation results of electroreduction disaccharide are reported in this paper.The possible electroreductionmechanism of sugars is proposed.更多还原
