Composition of Products of Birch Wood Deligniёcation by Hydrogen Peroxide in the Medium “Acetic Acid – Water – Catalyst TiO2”

The composition and structure of the solid and soluble products of birch wood deligniёcation by H2O2 in the presence of TiO2 catalyst were studied. The efёcient deligniёcation of wood proceeds at 100 °C and atmospheric pressure. The obtained microcrystalline cellulose (yield 48.2% mass.), has crystallinity index 0.81 and contain 93.7% mass. cellulose, 5.5% mass. hemicelluloses and 0.5% mass. lignin. Soluble products of birch wood peroxide deligniёcation are mainly presented by 4-O-methylglucuronoxylan (84% rel.), monosaccharides and they contain very few aromatic compounds.
