Study of Regularities and Optimization of the Process of Fir Wood Peroxide Delignification in the Medium of 'Acetic Acid – Water' in the Presence of Sulfuric Acid Catalyst
Autor: Olga V. Yatsenkova, Boris N. Kuznetsov, Andrei M. Skripnikov
Publikováno v: Journal of Siberian Federal University. Chemistry. :590-603
The work describes a one-stage method of cellulose obtaining from fir wood based on peroxide delignification of wood under mild conditions (100 °C, atmospheric pressure) in the presence of acetic acid, water and catalyst of 2% wt. H2SO4. The possibi

The Investigation of the Stability of Solid Acid Catalysts in the Process of Larch Arabinogalactan Hydrolysis in Aqueous Medium
Autor: Ivan P. Ivanov, Andrei M. Skripnikov, Olga V. Yatsenkova, Svetlana A. Novikova, Boris N. Kuznetsov
Publikováno v: Journal of Siberian Federal University. Chemistry. :282-295
The toxic and corrosive mineral acids are used traditionally in the processes of plant polysaccharides hydrolysis. The use of solid acid catalysts improves the environmental safety of hydrolysis processes and simplifies the separation of the catalyst
