Process for the preparation of sucrose-6-ester by esterification in the presence of solid superacid catalyst |
| abstract |
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 SO42---TiO2/Al2O3 or SO42---TiO2. 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 purification. TPSGA is de-esterified by sodium methoxide/methanol or sodium ethoxide/ethanol to give sucralose. |
