Title: PROCESS FOR THE PREPARATION OF SUCROSE-6-ESTER BY ESTERIFICATION IN THE PRESENCE OF SOLID SUPERACID CATALYSTAbstract: One embodiment of the present inventionis a process of making sucrose-6-ester from sucrose by transesterification in the presence of a solid super acid catalyst such as SO[err][err]--TiO[err]/Al[err]O[err] or SO[err][err] --TiO[err]. The sucrose-6-acetate is then chlorinated to afford sucralose-6-acetate, using BTC or thionyl chloride. Sucralose-6-acetate is converted into TPSGA for the purpose of purifica-tion. TPSGA is de-esterified by sodium methoxide/methanol or sodium ethoxide/ethanol to give sucralose.
