- Аннотация: The absorption of ozone by pine wood has been studied. The content of lignin (LG) and cellulose (CL) in lignocellulosic material (LCM) from ozonized wood was determined. The degree of polymerization of CL from LCM has been determined. LCM samples were examined by methods of IR spectroscopy and X-ray diffraction analysis. Ozonation of wood leads to the destruction of LG, which is characterized by a stoichiometric coefficient of 2 mol O3 /mol C9PPU LG; a degree of delignification of 40-42% is achieved. The delignification process is accompanied by the destruction of hemicelluloses and the amorphous part of the cellulose. An ozone specific absorption region corresponding to the most effective destruction of lignin with the least degradation of cellulose fiber has been established.
