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
