Abstract
The invention discloses a method for improving the yield of sucralose, including reacting sucrose to produce sucrose-6-acetate in the existence of an azo reagent as a catalyst and acetic acid as an acylating agent in a proper solvent; then reacting sucrose-6-acetate with a proper chlorinating agent to produce sucralose-6-acetate in a non-proton polar solvent with TCA as a catalyst; and at last, alcoholyzing sucralose-6-acetate in KOH/methanol to obtain sucralose.
