The composition and structure of the solid and soluble products of birch wood delignification by H 2 O 2 in the presence of TiO 2 catalyst were studied. The efficient delignification 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 delignification are mainly presented by
