FIELD: chemistry.
SUBSTANCE: water suspension of crushed aspen wood is put into a flow reactor and ozonised. Ozonation is carried out with concentration of ozone in the ozone-oxygen mixture equal to 90 mg/l, gas flow rate equal to 2-4 l/h and temperature of 20°C and hydromodulus between 0.1:1.0 and 1.6:1.0.
EFFECT: high quality of the cellulose intermediate product, low consumption of reagents, high ecological cleanness of the process.
