NOVEL PREPARATION OF 6-O-ACYL CHLOROSUCROSE FROM ANHYDROUS CHLORINATED REACTION MASS

摘要

A process is described for production of a chlorinated sucrose from a process stream containing a 6-O-protected chlorinated sucrose derived from chlorination of 6-O-protected sucrose wherein the process stream is treated under conditions which prevent or reverse deacylation of 6-O-protected chlorinated sucrose, extracting the same in a solvent, washing most of the dimethylformamide free from the solvent extract by repeated washing with saturated sodium chloride solution, isolating the 6-O-proetctetd sucrose as a pure fraction and obtaining a chlorinated sucrose by deacylating the same.
