Abstract

A process for purifying sucralose mainly includes a recrystallization step and an impurity washing step. In recrystallization, 10~80% sucralose dissolves in a cosolvent, then is precipitated to be 80~95% crystal utilizing a crystal-depositing agent. In the impurity washing step, said sucralose crystal is immersed in a selective solvent having very low solubility of sucralose, only dissolving the impurity. Next, the selective solvent is filtered out to obtain 95~99.9999% sucralose crystal. The process is able to purify the sucralose with low cost and high efficiency. The present invention further discloses a process of manufacturing sucralose including a purifying process.
