Conversion of Cellulose into Bio-fuels by Acidic Ionic Liquids

当纤维素在盐酸中加热时，得到容易转化为生物燃料的5-(氯甲基)呋喃。报道了利用酸性离子液体将纤维素转化为5-氯甲基呋喃甲醛的反应。将巨晶纤维素加入到[Hmim][Cl]-HCl(1：1)溶液中，得到均匀的混合物，然后将其引入含有1，2-二氯乙烷的烧瓶中。在65℃条件下连续搅拌提取42 h，可得到33%的5-氯甲基呋喃甲醛。

When cellulose is heated in hydrochloric acid, 5-(chloromethyl)furfiiral which is easily converted to the biofuel is obtained. We report the conversion of cellulose into 5-(chloromethyl)furfural utilizing acidic ionic liquids. Macrocrystalline cellulose was added to [Hmim][Cl]-HCl(1:1)solution to give a homogeneous mixture, which was introduced into a flask containing 1,2-dichloroethane. The solvent was kept at 65 ℃ with continuous stirring and extracted for 42 h. 5-(chloromethyl)furfural(33%) was isolated.
