Patent ID: 8609834

Claim:
A method for synthesizing sucrose-6-acetic ester, consisting of the following steps: (a) adding sucrose into a polar aprotic solvent and stirring the solvent to generate a suspension solution of sucrose, wherein said polar aprotic solvent is selected from the group consisting of: N,N-dimethylformamide, hexamethyl-phosphoric triamide, acetonitrile, and propionitrile; (b) adding acetylnitrile into said suspension solution and stirring the solution at a reaction temperature of acetyInitrile and sucrose of 20° C.-60° C.; (c) adding water into the reaction solution of step (b) and then concentrating it to generate a concentrated product; and (d) adding crystallization solvent into the concentrated product, stirring to dissolve it, and depositing for crystallization, then filtering and drying it to get a product of sucrose-6-acetic ester.
