SO_4^(2-)/TiO_2催化马来酸酐均聚反应研究

Study on Polymerization of Maleic Anhydride Catalyzed by SO_4^(2-)/TiO_2

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.

Polymerization of maleic anhydride was catalyzed by SO4^2-/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 SO4^2-/TiO2 had high catalytic activity when catalyzing polymerization of maleic anhydride. In addition, the catalytic mechanism was studied primarily.
