Mechanisms of Oxidative Degradation of Carbohydrates During Oxygen Delignification, 2002 Fall Technical Conference

Hydroxyl radicals, generated photochemically from hydrogen peroxide in aqueous base, have been shown to cleave directly glycosidic linkages in methyl β-D-glucoside and methyl β-cellobioside [1,2]. In this paper we show that hydroxyl radicals are responsible for the degradation of glycosidic linkages in 1,5-anhydrocellobitol and 2- methoxytetrahydropyran by substitution reactions displacing 1-deoxyglucose, D-glucose, tetrahydropyran-2-ol, and methanol. Once the glycosidic linkages are broken, reducing carbohydrates undergo a series of reactions forming aldonic acids and lower order aldoses in the same manner as described previously [1,2]. Under these same conditions, hydroxyl radicals degrade cellulose substantially as evidenced by viscosity loss.
