Abstract

The Debus-Radziszewski imidazole synthesis was adapted to directly yield long-chain imidazolium ionic liquids. Imidazolium acetate ionic liquids with side-chains up to sixteen carbon atoms were synthesised in excellent yields an on-water, one-pot reaction. The imidazolium acetate ILs acted as surfactants when dissolved in various solvents. The imidazolium acetate ionic liquids were also derivatised an acid metathesis to the chloride, nitrate, and hydrogen oxalate derivatives. The thermal behaviour of all the ionic liquids was determined thermogravimetric and calorimetric analysis.

摘要

德布斯-拉齐谢夫斯基咪唑合成法经过调整后可直接生成长链咪唑鎓离子液体。通过水相一锅法反应，以优异的产率合成了侧链含多达16个碳原子的醋酸咪唑鎓离子液体。醋酸咪唑鎓离子液体溶解于各种溶剂时可作为表面活性剂。醋酸咪唑鎓离子液体还通过酸复分解反应衍生为氯化物、硝酸盐和草酸氢盐衍生物。通过热重分析和量热分析确定了所有离子液体的热行为。
