N-正丁基-N-甲基咪唑-D-(-)-酒石酸手性离子液体制备研究

Study on the Preparation of N-butyl-N-Methyl Imidazolium-D-(-)-Tartrate Chiral Ionic Liquid

以天然手性化合物D-(-)-酒石酸为手性阴离子,分别通过树脂交换法和化学合成法制备了N-正丁基-N-甲基咪唑-D-(-)-酒石酸手性离子液体,并对产品纯度、结构及比旋光度进行检测.对两种制备方法进行了比较分析,得出:树脂交换法是获得高纯度离子液体的好方法,而化学合成法则适用于对纯度要求不高的离子液体的制备,并总结了两种方法的适用范围及优缺点.

Using Natural chiral compound D-（-）-tartaric acid as chiral anion , and applying resin exchange and chemical synthesis respectively, both produced N-butyl-N-methy imidazolium-D-（-）-. After detecting the product purity, structure and Specific rotation , a comparative analysis of the two preparation methods was made. the concluson was as follows： resin exchange is a good method to attain high-purity ionic liquids and chemical synthesis applies to the less demanding purity ionic liquids. At last, the paper discussed the advantages and disadvantages of the two methods.
