Popis:	The paper presents a mathematical formalization of regularities during the alkaline treatment of rice straw as one of the stages of oxidation-organosolvent pulping. The purpose of the research is to maximize the yield of technical pulp, to extract minerals and to remove lignin. It has been found out that the following input values are optimal: the duration of alkaline treatment of rice straw is 240 minutes; the concentration of alkali is 0.69 N. Under the given conditions of alkaline treatment with oxidation-organosolvent pulping, commercial pulp is produced with a yield of 58.8%, the mineral content being 0.05%, and residual lignin being 2.5% of bone dry raw materials. © 2018 CEUR-WS.
