Method for preparing sucralose without intermediate separation of crystalline sucralose-6-ester

摘要

The present invention provides an aqueous solution of sucralose and salts and impurities by deacylating the sucralose-6-ester directly before or after removal of the tertiary amide reaction carrier from the neutralized chlorination reaction mixture, from which sucralose It relates to a process for producing sucralose from sucralose-6-ester, which is recovered by extraction and preferably purified by crystallization.
