Abstract:
The present invention discloses a process for synthesizing sucralose, which comprises reacting sucrose with acetic anhydride in the solvent of a N-amide compound in the presence of an organic complex alkali metal salt catalyst to produce sucrose-6-acetate, and then chlorinating and deacetylating the sucrose-6-acetate to give sucralose. The present invention also discloses a process for purifying sucralose, which comprises purifying crude sucralose with one or more organic solvents to obtain purified sucralose.
