中文摘要：
采用两种离子液体1-烯丙基-3-甲基氯化咪唑（[Amim]C1）与1-丁基-3-甲基氯化咪唑（[Bmim]E1）分别与微晶纤维素（MCC）解结晶反应20、40与60min．X射线衍射技术（XRD）的分析结果表明，用[Amim]C1与[Bmim]C1处理MCC可使其结晶指数从90．2％分别降至72．4％与66．8％．x射线光电子能谱（XPS）的C1s、01s能谱峰分析显示，离子液体处理后，纤维素大分子中原有的化学键类型并没有明显改变，但相对含量有很大变化，C—OH键和C-OH…0键的相对含量变化均与结晶指数的变化高度相关，其相关系数分别为0．9990与0．9846．
英文摘要：
Two kinds of ionic liquids, namely, 1 -allyl-3-methylimidazolium chloride （ [ Amim ] C1） and 1 -butyl-3- methylimidazolium chloride （ [ Bmim ] C1）, were respectively used to decrystallize microcrystalline cellulose （MCC） for 20, 40 and 60 rain. XRD spectra show that, after the treatment with [ Amim ] C1 or [ Bmim ] C1, the crystalline index of MCC decreases from 90.2% to 72. 4% or to 66.8%. Moreover, XPS spectra indicate that, different from the relative content of chemical bonds, the chemical-bond type of cellulose macromolecules shows no obvious change after the decrystallization; and that the relative content changes of C--OH and C--OH…O are highly related to the variation of crystalline index, with the conelation coefficients being 0. 9990 and 0. 9846, respectively.
