ABSTRACT:
A process for preparing sucrose-6-ester is provided, which comprises electrolyzing an electrolyte solution containing sucrose, an acylating reagent and a halide catalyst. Also disclosed is a process for preparing sucralose, which involves the preparation and chlorination of sucrose-6-ester followed by deacylation of the molecule. The process of the invention can be more readily performed with a higher yield than those in the art.
