Process for the oxidation of starch |
摘要 |
A process for the oxidation of starch to obtain carbonyl-substituted starch using V, Cr, Mn, Fe, Co or Cu, wherein Fe and/or Cu are preferred as catalyst. The oxidation of the starch proceeds in quasi-dry form by spraying the dry starch with solutions containing hydrogen peroxide and/or the catalyst and mixing the moistened powder. Oxidized starch containing up to approx. 10 carbonyl groups per 100 glucose units is obtainable.
