| 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. |
| 关 键 词： | Bi-MCM- 对氯甲苯 氧化反应 对氯苯甲醛 |

| 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. |
| Keywords: | Bi-MCM-41 4-chlorotoluene oxidation 4-chlorobenzaldehyde |
