Abstract
The influence of conditions of birch wood oxidative delignification by hydrogen peroxide in acetic acid – water medium at atmospheric pressure in the presence of TiO2 catalyst on yield and composition of cellulosic product was studied. It was established that the content of lignin in cellulosic product reduces with the increase of H2O2 and CH3COOH concentrations in the reaction medium. Simultaneously there is a decrease in cellulosic product yield.
