The biphasic system enabled a simple separation of the resulting glucose aqueous solution and ionic liquid. Additionally, a fermentation inhibitor, 5-(hydroxymethyl)furfural, could be removed from the aqueous phase into the ionic liquid phase. The yield of glucose in cellulose hydrolysis was 12.9% at 190 °C. The distribution ratio of glucose in the aqueous phase was 0.98 with an ionic liquid/water ratio of 0.13 (w/w), indicating that most of the glucose was recovered into the aqueous phase. 5-(Hydroxymethyl)furfural was absorbed into the ionic liquid phase from the aqueous phase. The concentration of 5-(hydroxymethyl)furfural in the aqueous phase decreased from 37 to 1.9 mM, which was lower than the concentration at which fermentation is inhibited (24 mM). The acidic and hydrophobic ionic liquids did not decompose during the cellulose hydrolysis and could be recycled four times. © 2016 American Chemical Society., Embargo Period 12 months, 金沢大学ナノマテリアル研究所 / 金沢大学理工研究域生命理工学系}, pages = {3352--3356}, title = {Hydrolysis of cellulose using an acidic and hydrophobic ionic liquid, and subsequent separation of glucose aqueous solution from the ionic liquid and 5-(hydroxymethyl)furfural}, volume = {4}, year = {2016} }
