摘要
合成了碱性离子液体1-丁基-3－甲基咪唑（[bmim]OH），研究了其在苯甲醛与氰乙酸乙酯或哩二精的KnoPvenagel反应的应用。实验结果表明：在无溶剂条件下，反应物的物质的量比为1：1，离子液体占反应物的摩尔分数为20％，室温下搅拌，反应时间只需10～30min，产率可迭到85％～95％，后处理简单方便，离子液体可重复使用5次。
The basic ionic liquid 1-butyl＇--3-methylimidazolium hydroxide （[bminl]OH） was prepared. The application on the Knoevenagel reaction of ionic liquid was researched with aromatic aldehydes with malononitrile or ethyl cyanoacetate. The experimental results showed that, the reactants were stirred within 10-30 minutes under room temperature in the precence of ionic liquid with 20% mole fraction. In addition the product was obtained with 85-95% yields under no solvent. The procedure was simple and facile, and the ionic liquid could be recycled with five times.
