Improved process for purification of 6 acetyl 4,1',6' trichlorogalactosucrose and 4,1',6' trichlorogalactosucrose by chromatography on silanized silica gel

摘要

A reverse phase column chromatographic process of purification of 6-acetyl-4,1',6' trichlorogalactose and 4,1',6' trichlorogalactose is described which uses silanized silica as stationary phase and water or predominantly aqueous mixture derived from water and small proportion of organic solvents as a mobile phase.
