以N,N-二甲基甲酰胺为溶剂、SO42-/TiO2作催化剂,在加热回流条件下催化马来酸酐均聚反应.分别用XRD对催化剂、FT-IR对均聚产物进行了表征.实验结果显示:SO24-/TiO2对马来酸酐催化反应具有很高的催化活性.文章对催化机理进行了初步分析.
Abstract：Polymerization of maleic anhydride was catalyzed by SO42-/TiO2 using N,N-dimethyl formamide as solvent under the refluxing condition.The catalysts were characterized by XRD,and products were characterized by FT-IR method respectively.Experiment results showed that SO42-/TiO2 had high catalytic activity when catalyzing polymerization of maleic anhydride.In addition,the catalytic mechanism was studied primarily.
