A method for synthesizing sucrose-6-ester includes: (a) in the presence of a polar aprotic solvent, contacting an organic phosphine compound represented by formula I with sucrose and an organic tin compound; (b) removing water to obtain a reaction liquid containing a tin-sucrose adduct; and (c) contacting the reaction liquid containing the tin-sucrose adduct with an acid anhydride compound to prepare a sucrose-6-ester. In formula I, R 1 , R 2 , and R 3 each are a linear or branched alkyl having 1 to 20 carbon atoms, a cycloalkyl having 3 to 10 carbon atoms, or an aryl having 6 to 10 carbon atoms; moreover, the R 1 , R 2 , and R 3 are identical groups, partially identical groups, or different groups from each other. According to the method, the reaction conversion rate and selectivity are greatly improved; moreover, it is easy to realize industrial application. |
