| Abstract: | 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 100°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.
Part of this report was presented at the 58th Annual Meeting of the Japan Wood Research Society, Tsukuba, April 2008 |
