固载型过渡金属卟啉催化氧化烷烃的研究进展

Development of catalytic oxidization of alkanes by supported transition-metal porphyrin complexes

对固载型过渡金属卟啉在多相催化体系中氧化烷烃的现状进行综述,重点介绍了有机担体如阴离子交换树脂,无 机担体二氧化硅、蒙脱土上固载金属卟啉的方法及催化氧化烷烃的效果。固载金属卟啉容易分离,一定条件下,催化剂 的寿命较之液相催化剂有所延长,但是也存在反应诱导期长、催化剂制备复杂及容易从担体流失等缺点。

The development of catalytic oxidization of al-kanes by supported transition-metal porphyrins on the heterogeneous system is introduced in the present paper. The reaction results and preparation methods of porphyrins on various supports such as ion-exchange resin,silica, clay are specified . In general , the catalyst is comparatively easy to be separated on the reaction system ,and has some good results to some extent . On the other hand , it is hard to be produced and easy to lose from the support.
