Process for decolorizing aqueous sugar solutions via adsorbent resins, and desorption of color bodies from the adsorbent resins

摘要

A process for decolorizing an aqueous sugar solution by contacting the solution with an absorbent resin, wherein the adsorbent resin is a macroporous copolymer being post-crosslinked in a swollen state in the presence of a Friedel-Crafts catalyst and functionalized with hydrophilic groups prior to contact with the aqueous sugar solution.
