| 摘 要： | 在隔离式电解槽中，以制备的泡沫Pb为阴极，Pt丝为对电极，饱和甘汞电极（SCE）为参比电极，研究了不同电解体系的伏安曲线和蒽的阴极电化学加氢行为.实验发现：在已研究的体系中，蒽阴极电解加氢为二氢蒽，其中CH3CN+EtOH+H2O+Bu4NBr是加氢效果较好的电解体系.进一步研究CH3CN+EtOH+H2O+Bu4NBr电解体系中H2O浓度、溶剂组成和支持电解质Bu4NBr的浓度以及温度等因素对蒽电解催化加氢效果的影响，结果表明较理想的电解体系组成为：［H2O］＝5.5mol•L-1，［CH3CN］/［EtOH］＝2/1(v/v)，［Bu4NBr］＝0.50mol•L-1，温度为35℃，在该条件下，电解反应6 h，二氢蒽的产率可达91.37％.

| Abstract: | Electrochemical hydrogenation of anthracene was carried out in a divided three-electrode cell with spumous Pb as cathode and Pt as anode.The curves of current-potential and the effectiveness of hydrogenation in CH3CN+EtOH+H2O+Bu4NBr,EtOH+H2O+Bu4NBr,DMF+H2O+Bu4NBr,and DMF+EtOH+H2O+Bu4NBr electrolysis systems were studied.It was shown that the CH3CN+EtOH+H2O+Bu4NBr system was suitable for electrochemical hydrogenation of anthracene,and the product was dihydroanthracene in these systems.Furthermore,the effects of constitutes of solvents, water content, supporting electrolyte, and temperature were investigated.The optimum conditions found are potential=-1.9V,［CH3CN］/［EtOH］＝2/1(v/v)，［H2O］＝5.5mol•L-1,［Bu4NBr］＝0.50mol•L-1 and T=35℃.The yield of dihydroanthracene is 91.37% for six hours electrolysis in these conditions. |
