摘要

Abstract

With Pt as anode

saturated calomel electrode as reference electrode

the effects of different electrolytic cells

electrolytic solvents

supported electrolytes and cathode materials on electrochemical hydrogenation of lignin were studied.The results showed that electrolytic hydrogenation of lignin was better in the electrolytic system of DMF+EtOH+H2O+Bu 4NBr with sponge Pb as cathode in the divided electrolytic cell than in the other selected electrolytic systems in terms of ultimate analysis and soft point of hydrogenated lignin.After electrolysis

the hydrogen content and the atomic ratio of hydrogen to carbon of hydrogenated lignin can increase by 0.81 and 0.02 respectively

but the soft point of hydrogenated lignin can decrease by 9℃. At the same time

current dependence of potential indicated that electrolytic hydrogenation of lignin can be carried out in this electrolytic system.
