摘要
间硝基甲苯经液相模拟空气氧化制得间硝基苯甲酸。重点讨论了催化剂用量、反应温度和氧气浓度对反应速度的影响。在温度130～145℃、催化剂用量8～12g／L、氧气分压0．2～0．4MPa的最佳操作条件下，反应理论收率＞99％。
m-Nitrobenzoic acid was preparated from m - nitrotoluene by liquid - phase oxidation with simulated air. The influence of the catalyst amount, reaction temperature and O2 concentration on the reaction rate was emphatically discussed. Theoretical yields of >99% were obtained under the optimal conditions of 130～145℃ operation temperature, 8～12g/L catalyst amount and 0. 2～0. 4 MPa O2 partial pressure.
