烃类氧化是一个由许多平行、串联等反应构成的复杂自由基链式过程,通常分为链引发、链传递和链终止三个主要阶段。近些年来,催化在烃类液相氧化中的应用得到了重视,首先是制备芳香族羧酸的钴-溴催化剂。但至今钴-溴催化体系的研究多限于烷基芳香烃的氧化,对饱和烃的报导极少。 Hydrocarbon oxidation is a complex free radical chain process consisting of many parallel, series reactions. It is usually divided into three main stages: chain initiation, chain transfer and chain termination. In recent years, attention has been paid to the application of catalysis in the liquid phase oxidation of hydrocarbons. The first is the preparation of a cobalt-bromine catalyst for aromatic carboxylic acids. However, up to now, the research of cobalt-bromine catalytic system has been mostly limited to the oxidation of alkyl aromatic hydrocarbons, and few reports on saturated hydrocarbons.
