中文摘要:
      研究了微晶纤维素在Bola 型咪唑基有机硅离子液体中的溶解性能。通过偏光显微镜、傅里叶变换红外光谱、X射线衍射、扫描电子显微镜和热重分析对再生前后微晶纤维素进行了表征。结果表明,Bola型咪唑基有机硅离子液体对微晶纤维素有较好的溶解能力,且不发生其他衍生化反应。微晶纤维素开始热降解温度为320 ℃,而再生微晶纤维素开始热降解温度为234 ℃,这是再生微晶纤维素发生了晶型的变化而导致其热稳定性有所下降。
英文摘要:
      The dissolution of microcrystalline cellulose in Bola-imidazolium based silicone ionic liquids was investigated. The both original microcrystalline cellulose and regenerated microcrystalline cellulose from Bola-imidazolium based silicone ionic liquids were characterized by polarizing microscope (POM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscope (SEM) and thermogravimetry (TGA). The results show that the Bola-imidazolium based silicone ionic liquids can dissolve microcrystalline cellulose effectively. The decomposed temperature of regenerated microcrystalline cellulose is 234 ℃ and decreased in comparison with decomposed temperature (320 ℃) of microcrystalline cellulose, caused by changing of their crystal type.
