| Abstract: | p-Nitrobenzoic acid was prepared by using manganese dioxide（MnO2） and N-hydroxyphthalimide（NHPI） as catalysts to efficiently catalyze the oxidation of p-nitrotoluene.The conditions of the oxidation reaction were optimized.It was found that in the presence of 10%（molar ratio） NHPI and 10%（molar ratio） MnO2 as the catalysts,p-nitrotoluene was converted at a rate of 97% and p-nitrobenzoic acid was harvested at an isolated yield of 89% after 4 h of catalyzed oxidation at 110 ℃ under an oxygen pressure of 0.4 MPa. |
