Abstract

A method for production of organosolvent pulp includes introduction to boiler of chaff of cellulose-containing raw material and alkaline-sulfate-alcohol cooking liquor that contains 25% of inorganic chemical substances and 0.1% of anthraquinone from weight of absolute dry substance, boiling is carried out at hydro-modulus of 6:1. Inorganic chemical reagents contain sodium sulfite in amount of 15...22.5% and sodium carbonate in amount of 2.5...10 % of weight of absolute dry material, boiling is carried out at temperature of 120...160 °C during of 90...150 minutes.
