Alkaline degradation of model compounds related to beech xylan

To address the chemical behavior of beech xylan (O-acetyl-4-O-methyl-glucuronoxylan) under alkaline conditions, three model compounds, 2-O-methylxylobiose (1), aldobiouronic acid (4-O-methyl-?-D-glucopyranosyluronic acid-(1?2)-xylose, 2), and aldotriouronic acid (4-Omethyl-?-D-glucopyranosyluronic acid-(1?2)-?-D-xylopyranosyl-(1?4)-D-xylose, 3), were subjected to strong alkaline conditions equal to those used for the industrial production of viscose (18% NaOH, 43°C)...
