摘要: 本文报道了羧甲基-β-环糊精的一种简便合成方法,并研究了羧甲基-β-环糊精对卤代芳烃类化合物的增溶作用.羧甲基-β-环糊精能与水以任意比例互溶,其水溶液对卤代芳烃有明显的增溶作用.增溶作用的大小主要与卤代芳烃的疏水性及分子的几何形状与环糊精空腔的匹配程度有关.Abstract: A simple synthetic method for the synthesis of a cyclodextrin derivative carboxymethyl-β-cy-clodextrin is reported in this paper. Trie application of carboxymethyl-β-cyclodextrin on the solubi-lization of halogenated aromatic hydrocarbons is investigated. Carboxymethyl-β-cyclodextrin can be dissolved in water in unlimited amount. Its water solution can enhance the water solubilities of halogenated aromatic hydrocarbons significantly. The solubilization power of carboxymethyl-β-cyclodex-tnn are depended on the lipophilisity of the halogenated aromatic hydrocarbon and the fitness of the molecular size to the cavity of the cyclodextrin.
