Abstract
รูปลักษณะหนึ่งของการประดิษฐ์นี้ คือ กระบวนการของการเตรียมซูโครส-6-เอสเทอร์ จากซูโครสโดยทรานส์เอสเทอริฟิเคชัน ในการมีอยู่ของคะตะลิสต์ชนิดซูเปอร์แอซิดที่เป็นของแข็ง เช่น SO42---TiO2/AI2O3 หรือ SO42---Tio2 จากนั้น ซูโครส-6-อะซิเตต จะถูกคลอริเนทเพื่อให้ ซูคราโลส-6-อะซิเตต โดยใช้ BTC หรือ ไธโอนิล คลอไรด์ เปลี่ยนซูคราโลส-6-อะซิเตต ไปเป็น TPSGA สำหรับความมุ่งหมายของการทำให้บริสุทธิ์ TPSGA จะผ่านดีเอสเทอริฟิเคชันโย โซเดียม เมทธอกไซค์/เมทธานอล หรือ โซเดียม เอทธอกไซค์/เอทธานอล เพื่อให้ซูคราโลส One feature of this invention is the process of preparing sucrose-6-esters. From sucrose by trans esterification In the presence of solid superacid catalysts such as SO42 --- TiO2 / AI2O3 or SO42 --- Tio2, then sucrose-6-acetate. Will be chlorinated so that Sucralose-6-acetate, using BTC or thionyl chloride, converts sucralose-6-acetate to TPSGA.For purification purposes, TPSGA will pass DST. Arrification yosodium methoxide / methanol or sodium ethoxide / ethanol For sucralose
