摘　　要：介绍了现阶段钴盐催化甲苯液相选择氧化所使用的各种工艺、钴盐和钴盐复合催化剂在有无溶剂或助剂作用下的催化情况。探讨了现阶段钴盐催化氧化甲苯所存在的催化剂活性,甲苯转化率、产品选择性以及纯度等问题,指出了未来钴盐催化氧化甲苯的发展方向应该是寻求一种高效绿色并且可以提高甲苯转化率、产物选择性的钴盐催化剂。The various processes of the use of cobalt salts as catalysts for the oxidation of toluene and the catalytic effect with or without solvent and initiator are reviewed. Pointing out the existing problems in cobalt salts as catalysts for the oxidation of toluene at the present stage,such as active of the catalyst,toluene conversion and product selectivity as well as product purity. In the future,the development direction of cobalt salt catalyzed oxidation of toluene should be to seek a highly efficient and green cobalt salt catalyst which can improve the conversion rate of toluene and the product selectivity,and can meet the requirements of green production.
