摘要： 合成了一系列 Bi 掺杂的 MCM-41 介孔分子筛, 运用电感耦合等离子体原子光谱, X 射线衍射, N2 吸附脱附, 透射电镜和紫外可见光谱对其进行了表征, 并将其用于以 H2O2 为氧化剂, 乙腈为溶剂的对氯甲苯选择氧化反应中. 结果表明, Bi-MCM-41 即便在底物量较大时也表现出较高的催化活性. 浓缩反应液的检测结果表明, Bi 在反应过程中无明显流失, 同时该催化剂具有良好的循环使用性能.

Abstract: A series of bismuth incorporated MCM-41 mesoporous samples were synthesized and characterized by inductive coupled plasma emission spectrometer (ICP), X-ray diffraction, N2 adsorption/desorption, transmission electron microscopy, and UV-Vis spectroscopy. These samples catalyzed the selective oxidation of 4-chlorotoluene efficiently even on a large scale with H2O2 as oxidant in acetonitrile. No bismuth was detected by ICP in the condensed reaction mother liquid, and the recycle test proved the catalyst was stable.

Key words: Bi-MCM-41, 4-chlorotoluene, oxidation, 4-chlorobenzaldehyde
