Abstract Direct hydroxylation of benzene using molecular oxygen is an engaged approach to yield of phenol as a valuable compound with numerous applications. In the present research, highly selective benzene hydroxylation was successfully carried out in the presence of O2 using vanadyl phthalocyanine implanted onto the chloro-functionalized SBA-15 as a robust catalyst. Also, the effect of water as a co-solvent was investigated and it was concluded that the mixed solvent (CH3CN-H2O) can play a remarkable role in the development of the reaction progress due to its ability to act as an axial ligand. Then, the oxidation of benzene using CH3CN and CH3CN-H2O was kinetically investigated.

氧代钒 (IV) 酞菁植入改性 SBA-15 作为催化剂在乙腈-水介质中苯直接羟基化为苯酚：动力学研究

摘要 使用分子氧直接羟基化苯是一种生产苯酚的有效方法，苯酚是一种具有多种应用的有价值的化合物。在本研究中，在 O2 存在下，使用植入氯官能化 SBA-15 上的酞菁氧钒作为强效催化剂，成功地进行了高选择性苯羟基化。此外，还研究了水作为共溶剂的影响，得出的结论是，混合溶剂 (CH3CN-H2O) 由于能够充当轴向配体，因此在反应进程的发展中可以发挥显着的作用。然后，动力学研究了使用 CH3CN 和 CH3CN-H2O 氧化苯。
