以稻草为原料采用微波-超声辅助水解氧化法制备稻草微晶纤维素，运用傅立叶红外光谱和X射线衍射等对微晶纤维素产物进行了初步表征和分析；扫描电镜观察了稻草纤维素和微晶纤维素。结果表明：微波-超声辅助法制备的微晶纤维素保持纤维素的化学结构特征，形态上由松散状变为较规则的排列，纤维素的无定形区被大部分除去。微波-超声辅助水解氧化法制备微晶纤维素工艺条件在反应时间与消耗能量方面明显低于传统方法。

Rice straw as the original materials,the microwave-ultrasonicmethod were used to prepare micro-crystalline cellulose(MCC)production.Determine the process conditions of preparation of microcrystalline cel-lulose.The physicochemical properties of MCC were studied by means of fourier transformed infrared(FT-IR) and X-ray diffraction(XRD). Useing scanning electronic microscopy(SEM)to observe the surface form of mi-crocrystalline cellulose diffraction.The results showed that the MCC prepared from rice straew keep the chemical structure characteristics of cellulose,but the surface had partial change to orderliness and most amorphous(disordered)phases were removed. Cornpared with conventional preparation method,the reaction time and energy consumption of microcrystalline cellulose(MCC)by Microwave-Ultrasonic-assisted Method were shortened greatly.
