摘要：

温和条件下，运用循环伏安法研究了1-丁基-3-甲基咪唑四氟硼酸盐 (BMIMBF₄) 离子液体中苯甲醛在Ag电极上的电化学还原行为.结果显示，苯甲醛的还原峰在 -1.8 V (vs.Ag).以Ag片作工作电极，Mg棒作牺牲阳极，在单室型电解槽中恒电流还原苯甲醛制备苯甲醇，收率为70%，选择性为100%.

关键词： 电化学还原, 离子液体, 苯甲醛, 苯甲醇

Abstract:

A new electrochemical procedure for the electrocatalytic reduction of benzaldehyde in ionic liquid，1-butyl-3-methyllimidazoliumtetrafluoborate (BMIMBF₄)，to phenylmethanol was investigated for the first time.The experiment was carried out in undivided cell under mild conditions，and the use of volatile and toxic solvents and catalysts，as well as any other additional supporting electrolytes，was avoided.The electrochemical reduction behavior of benzaldehyde in BMIMBF₄ had been studied by cyclic voltammetry with a reduction peak at -1.8 V (vs.Ag).Phenylmethanol was obtained with 70% yield and 100% selectivity，by typical electrolyse procedure.

Key words: electrocatalytic reduction, ionic liquid, benzaldehyde, phenylmethanol
