研究了日本山毛榉(Fagus Crenata)在能溶解纤维素的离子液体1-乙基-3-甲基咪唑氯([C2mim][Cl])中的反应。虽然木质素和纤维素、半纤维素等多糖都可以在100摄氏度左右的处理温度下液化，但多糖的液化主要发生在[C2mim][Cl]处理的开始。随着处理的继续，木材中的纤维素结晶度逐渐降低。溶解后的聚合物被解聚为低分子量化合物。结果表明，[C_2mim][Cl]是木材组分液化和解聚的有效溶剂和试剂。
Reaction of Japanese beech (Fagus crenata) in an ionic liquid, 1-ethyl-3-methylimidazolium chloride ([C2mim][Cl]), which can dissolve cellulose, was investigated. Although both lignin and polysaccharides such as cellulose and hemicelluloses can be liquefied at a treatment temperature of around 100A degrees C, the liquefaction of polysaccharides mainly occurs at the beginning of the treatment with [C2mim][Cl]. Cellulose crystallinity in the wood was gradually broken down as the treatment continued. The solubilized polymers were depolymerized to low molecular weight compounds. The results indicate that [C2mim][Cl] is an effective solvent and reagent for the liquefaction of wood components and subsequent depolymerization of them.
