Catalytic oxidation and carboxy-alkylation of carbohydrates

摘要

Converting carbohydrates into carboxylates or polycarboxylates is an obvious way of upgrading renewables.The (poly)carboxylates obtained may display unique properties or may enter the competition with fossil-based materials such as poly-acrylates.Moreover,there's a substantial price gap between bulk polysaccharides,such as starch,and natural 6-carboxy-polysaccharides,such as alginate and pectin.Furthermore,it may be noted that molecular mass increases upon oxidation or carboxy-alkylation.
