摘要: Direct conversion and NMR observation of cellulose to glucose and 5-hydroxymethylfurfural (HMF) catalyzed by the acidic ionic liquids
研究领域[WOS]: Chemistry
英文摘要: The hydrolysis of cellulose was catalyzed over a variety of acidic ionic liquids (ILs). It is found that the hydrolysis activity is directly associated with the acidity of catalysts, as evidenced by IR spectroscopy. (13)C NMR characterization results confirm the majority product of cellulose hydrolysis is glucose, and the resulting carbohydrates undergo further degradation, possibly also catalyzed by the acidic ILs, to 5-hydroxymethylfurfural (HMF). Moreover, in situ (13)C NMR measurements clearly exhibit that the evolution of products is dependent on the reaction process. we attempt to study the kinetics of cellulose hydrolysis over the most active catalyst of [C(4)SO(3)Hmim]HSO(4) at different temperatures (80-120 degrees C) to obtain the important kinetic parameters such as apparent activation energies of consecutive reaction steps.
