摘要：

本文采用羟基活化的方法对β-环糊精树脂进行活化,之后通过一步反应引入季铵基功能基团制得了一类新型的β-环糊精聚合物.考察了反应体系NaOH浓度,反应温度、反应时间、加料顺序及体系溶剂种类对树脂活化程度的影响.结果表明此种制备方法简便易行,用此方法可合成出多种季铵盐型β-环糊精树脂-对这类新型树脂的相转移催化性能的研究表明,树脂对硫氰酸苄酯具有较好的催化性能,催化量的树脂即可使产率显著提高.

Abstract:

Cyclodextrin resin with quaternary ammonium salt group was synthesized by activation cyclodextrin polymer with epichlorohydrm under alkali condition. The influences of experimental conditions, concentration of NaOH, reaction temperature, reaction time and other conditions, on activating results were studied in detail. The results show that the preparation method is very easy and various kinds of quaternary anrmonium cyclodextrin resins can be synthesized by this method. These resins can notably catalyzed the reaction of benzyl chloride with KSCN to produce benzyl thiocyanate.

Key words: Cyclodextrin resin, Phase transfer catalyst, Activation, Quaternary ammonium salt, Benzyl thiocyanate, Synthesis
