AbstractIn this paper, the kinetics of acid-catalyzed cellulose hydrolysis in ionic liquids (ILs) was investigated by using 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) as the model IL General kinetic equations for the formation of glucose as well as cellooligomers were constructed at a molecular level, assuming that cellulose is fully dissolved to form a homogenous solution and that the scission of the glycosidic bond occurs randomly within the cellulose chain. Experimental data were well fitted according to these equations. Variations of kinetic parameters in the presence of different water content indicated that water behaved also as a base to decrease the acidity of the reaction medium. More importantly, it offered a profile of the evolution of cellooligomers. These results provided insights into the detailed mechanisms of cellulose hydrolysis in a non-aqueous, homogenous environment and should be valuable for developing strategies to depolymerize lignocellulosic biomass.
