摘要
Abstract
Sucrose-6-acetate was synthesized based on chlorination of vilsmeier reagent by thionyl chloride, which was prepared from sucrose via selective esterification, and the structure was confirmed by IR, 1H NMR;The studies on the process of syntheses show that vilsmeier reagent prepared prior is necessary to increase the yield of chlorination; the most excellent condition for dichloro-substituted reaction is at 98-100℃ for 6h. Chloride reaction solution was extracted with dichloromethane and then crystallized with ethyl acetate-water in 41% yield. The optimized process of chlorination was simple and more easy to control and suitable for industrial production.关键词
