摘要

以硅胶和蒙脱土为原料,用硅烷偶联剂进行功能化,制备了固定化催化剂。与金属离子的配合物容易形成。研究了固定化催化剂对碳氢化合物的双氧氧化反应。环己烷在常温常压下氧化生成环己醇(主要)和部分环己酮。采用钴离子固定化蒙脱土催化剂,在锂离子存在下,观察了乙苯中乙基非活化β位的双氧氧化反应。

Functionalization of silica gel and montmorillonite by silane coupling reagent, IV. Application as immobilized catalysts in dioxygen oxidation of organic compounds

Immobilized catalysts were prepared from silica gel and montmorillonite functionalized by silane coupling reagents. Complexes with metal ions were easily formed. The dioxygen oxidation of hydrocarbon using the immobilized catalyst was investigated. Cyclohexanol (mainly) and some cyclohexanone were produced by the oxidation of cyclohexane at ordinary temperature, under atmospheric pressure. Dioxygen oxidation of the non-activated β-position of the ethyl group in ethylbenzene was observed in the presence of cobalt ion-immobilized montmorillonite catalyst in the presence of lithium ion.
