摘要: 在隔离式电解槽中,以Pt作阳极,泡沫铅(SPb)作阴极,饱和甘汞(SCE)作参考电极, DMF+EtOH+Bu4NBr+H2O作电解加氢体系,测定了木素电解加氢的伏安曲线,用Quasi-Newton数值回归法推导了木素电解加氢反应动力学模型。结果表明:在阴极电位V=-1.7~-2.8V之间,木素可进行电解加氢反应。木素电解加氢反应的动力学模型为

Abstract: In the divided electrolytic cell, with Pt as a anode, SPb as a cathode, sareturated calomel electrode as a reference electrode and DMF+EtOH+Bu4NBr+H2O as a elletrolytic system, the curve of cathode potential-electrical current of electrochemical hydrogenation of lignin was investigated, by which electrolytic reactive kinetic model of lignin was established in this electrolytic system. The reactive kinetic model of electrochemical hydrogenation of lignin was as follows (V=-1.7V ~-2.8V)
