Comparison of monopersulfuric acid and sulfuric acid as prehydrolysis reagents for high-purity cellulose production from Japanese cedar via soda–anthraquinone (soda–AQ) cooking and totally chlorine-free (TCF) bleaching

Journal of Wood Science
Prehydrolysis/soda–anthraquinone (AQ) cooking has emerged as a promising strategy for the production of high-purity cellulose; however, optimization of the prehydrolysis stage is still required.
