摘要
制备了一种具有高储氢容量的储氢材料——氨硼烷,研究了氨硼烷对苯乙酮、苯甲酰乙酸乙酯、水杨醛、2-乙基-2-己烯醛等四种羰基化合物的还原反应,考察了离子液体对反应的影响,对产物结构进行了鉴定。结果表明,以水为溶剂,氨硼烷可以选择性还原这四种羰基化合物,离子液体能够较好的促进氨硼烷对羰基化合物的选择性还原,使反应速率提高,反应时间缩短,并且离子液体可循环使用。
A kind of high hydrogen storage material, ammonia borane, was prepared. The carbonyl com- pounds such as acetophenone, benzoyl acetate, salicylaldehyde and 2-ethyl-2- hexenal were reduced by am- monia borane. The influence of ionic liquid on the reduction reaction was investigated. The structure of the target products was confirmed. The results indicated that the carbonyl compounds could be reduced by am- monia borane selectively in water. The selective reduction of carbonyl compounds was promoted by ionic liquid. The rate of reaction was enhanced and the reaction time was shortened. The ionic liquid could be recycled.
