A cellulose sulfonate catalyst (HS-cellulose sulfonate) with high stability, excellent catalytic activity and high acidity value (about 1.55 mmol g) was successfully prepared by SO gas phase sulfonation. The basic morphology and nanostructure of the catalyst were determined by HRTEM, XRD, IR, TG, In addition, the catalyst was applied to the catalytic reaction of a dihydroquinazolinone derivative and a xanthene compound, and very valuable results were obtained. The development and preparation of cellulose sulfonate catalysts provide a good approach for the development and application of cellulose, and also an important application of green organic catalytic synthesis methodology.
通过SO气相磺化成功制备了一种具有高稳定性、优异催化活性和高酸度值（约1.55 mmol g）的纤维素磺酸盐催化剂（HS-纤维素磺酸盐）。采用高分辨透射电子显微镜（HRTEM）、X射线衍射（XRD）、红外光谱（IR）、热重分析（TG）对催化剂的基本形貌和纳米结构进行了表征。此外，将该催化剂应用于二氢喹唑啉酮衍生物与呫吨化合物的催化反应，获得了非常有价值的结果。纤维素磺酸盐催化剂的开发与制备为纤维素的开发与应用提供了一条良好途径，也是绿色有机催化合成方法的重要应用。
