Abstract

Influence of the small quantities by chamois of the sulfuric acid, dioxide silicon and sulfuric sodium on the formation peracetic acids in medium «CH3COOH – H2O2 – H2O» and on the following delignification wheat straw Национальная ассоциация ученых (НАУ) # 66, 2021           45

got by oxidants solution at the 90 oC was studied. Diluted sulfuric acid is effectively catalyzing both processes, but reduce yield of the technical cellulose because of hydrolysis of slight-hydrolyzing polysaccharides. Efficiency of heterogenous catalyst SiO2 and promoter Na2SO4 is low.
