Abstract

Main regularities of aspen-wood delignification in the medium “acetic acid –hydrogen peroxide – sulfuric acid catalyst” have been established. The optimal conditions of delignification process (temperature, time, liquid to solid ratio, reaction mixture composition) were selected. They supply the high yield of cellulosic product with low content of the residual lignin.
