Abstract
In copending SN 2,114,180, a process for producing substantially pure sucralose pentaester from a mixture of 6-O-acyl-4,1',6'-trichloro-4,1',6'-trideoxyqalactosucrose in a reaction medium comprising a tertiary amide is described wherein said process comprises the steps of:
(a) recovering the 6-O-acyl-4,1',6'-trichloro-4,1', 6'-trideoxygalactosucrose from said mixture;
(b) peracylating the 6-O-acyl-4,1',6'-trichloro-4,1',6'trideoxygalactosucrose product of step (a) to produce thereby 4, 1',6'-trichloro-4,1',6'-trideoxygalactosucrose pentaester; and (c) crystallizing the 4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose pentaester product of step (b) to produce substantially pure 4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose pentaester.
This application is for a specific sucralose pentaester product that can be obtained from the above process, namely 6-O-benzoyl-4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose tetraacetate.
