| 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. |
