Abstract
Changes in the chemical composition of aspen wood after grinding in the ball, planetary, and vibrational centrifugal mills are estimated from the copper number, contents of water-soluble substances, monosaccharides in water-soluble substances, and the amount of easily hydrolyzed polysaccharides. It is stated that the destruction of polios and lignin occurs more intensively during the grinding of wood in the presence of sodium hydroxide.
