Abstract

It was shown, mechanochemical treatment of aspen wood in aqueous medium with planetary activator mill type AGO - 2leads to increase in activated samples yield of easy - hydrolyzed polysaccharides by 2,2 times, to decrease in residual lignin in 2,1times and heavy hydrolyzed polysaccharides by 2,8 times as compare to an initial wood. According to X-ray data, the activation and the following hydrolysis processes are considerably influenced on the supramolecular structure of lignocelluloses matrix.
