| 摘 要： | 探索两步法合成1-丁基-3-甲基咪唑甘氨酸离子液体(bmim]Gly)的反应条件.第一步，采用阴离子树脂静态交换法由1-丁基-3-甲基咪唑溴盐(bmim]Br)与强碱性阴离子树脂生成中间产物1-丁基-3-甲基咪唑氢氧化物(bmim]OH)，通过单因素实验获得其最佳交换条件；第二步，bmim]OH与甘氨酸(Gly)反应，经脱水、洗涤后得目标产物.对产物进行核磁(1H NMR)和红外(IR)表征，结果表明产品纯度较高.与动态合成法相比，静态法合成bmim]Gly操作简便，节水省时，有助于实现氨基酸离子液体合成过程的绿色化和工业化.

| Abstract: | The 1-butyl-3-methylimidazolium glycine acid salt(bmim]Gly) was prepared by two steps.The first step,the intermediary,1-butyl-3-methylimidazolium hydroxide (bmim]OH) was prepared by 1-butyl-3-methyl imidazolium bromide (bmim]Br) through a static anion ion exchange.The optimum reaction conditions were obtained by single factor experiments.The second step,the bmim]OH and glycine were mixed and reacted,then were dried under vacuum and washed with methanol,to form high purity product.The structure of product was confirmed and characterized by 1H NMR and IR.Compared with dynamic preparation method,the proposed static method is simple in operation and rapid in production rate,and consumes less leaching water and energy,so it promotes the preparation of the amino acid ionic liquid in a more green and industrialized direction. |
