蔗糖-6-乙酸酯的合成方法研究
Study on the Synthesis of Sucrose-6-acetate
【摘要】 采用高效液相色谱法指示反应进程 ,对蔗糖 - 6-乙酸酯的合成方法进行了系统研究。实验结果表明 ,二丁基氧化锡催化酯化法与原乙酸三甲酯酯化法相比 ,收率高 ,产物纯度高 ,催化剂和溶剂可回收重复使用 ,产物可不经分离直接用于下一步反应 ,是目前较理想的合成蔗糖 - 6-乙酸酯的方法。
【Abstract】 Systematic study was made on the synthesis method of sucrose 6 acetate, and the reaction was monitored by HPLC. The results showed that dibutyltin oxide was a better catalyst than trimethylorthoacetate, giving higher yield and purer product. Moreover, the catalyst and solvent could be reused, and the intermediate product could be used directly in the next reaction without purification. The esterification catalyzed by dibutyltin oxide was an ideal method for synthesizing sucrose 6 acetate by now.
