摘　　要：为寻求绿色的对硝基甲苯氧化工艺,采用负载在活性炭表面上的四羧基钴酞菁为催化剂,研究了对硝 基甲苯在碱性介质中的非均相氧气液相氧化反应,发现负载的四羧基钴酞菁的催化活性明显优于未负载的四羧 基钴酞菁,而且活性炭载体的比表面积越大,催化效果越好.在55℃、2.0 MPa氧气压力下,对硝基苯甲酸的收 率达到87.6％.该氧化方法工艺简便、产物易分离,因此具有良好的潜在应用前景.In order to find a green oxidation process of p-nitrotoluene, its oxidative reaction by oxygen in alkaline liquid system catalyzed by cobalt-tetracarboxylphthalocynine, which was deposited on activated carbon black, has been studied in this paper. It was found that cobalt-tetracarboxylphthalocynine loaded on activated carbon black was more active than that unloaded, meanwhile the bigger the specific surface of activated carbon black is, the more the activity of the catalyst is. The highest yield of p-nitrobenzoic acid was 87.6% when the reaction temperature was 55℃ and the oxygen pressure was 2.0 MPa. This process has advantage of simple operation and easy separation of product.
