Abstract:
1. A process comprising, in order, the steps of: (a) providing a first reaction mixture comprising sucrose, a reaction vehicle, and an organotin-based acylation promoter; (b) removing from the first reaction mixture water produced by reaction between sucrose and the organotin-based acylation promoter to afford a second reaction mixture; and (c) adding a carboxylic acid anhydride to the second reaction mixture to afford a third reaction mixture, thereby producing a sucrose-6-ester; in which: wherein a non-polar co-solvent is not added during step (b), and wherein the first reaction mixture and/or the second reaction mixture consist essentially of sucrose, polar aprotic solvent, the organotin-based acylation promoter, and/or their reaction products.
