| Abstract: | 4-Nitrobenzoic acid was prepared in 75% yield by manganese sulfate catalyzed liquid phase oxidation of 4-nitrotoluene with oxygen. The reaction was carried out in morpholine in the presence of potassium hydroxide under atmospheric pressure. Effects of reaction conditions such as reaction temperature, time, kinds of solvents, amounts of manganese sulfate, potassium hydroxide and morpholine and reaction mechanisms were discussed. |
