Title:
CHROMATOGRAPHIC PURIFICATION OF CHLORINATED SUCROSE
Document Type and Number:
Japanese Patent JP2010090160
Kind Code:
A
Abstract:

To provide a process for chromatographic purification of a chlorinated sucrose such as sucralose known as an extremely strong sweetener.

There is provided a process for separating, in a liquid phase, a reaction mixture comprising the first chlorinated sucrose and at least one additional component selected from the group consisting of at least one other chlorinated sucrose different from the first chlorinated sucrose, salt and solvent, by injecting the reaction mixture onto a fixed bed of a solid adsorbent and treating with a desorbent such that: (a) the first chlorinated sucrose passes through the adsorbent at a rate to generate the first recoverable product stream rich in the first chlorinated sucrose, and (b) at least one of the additional components passes through the adsorbent at a rate different from the above rate to generate at least the second recoverable stream rich in the additional component.
