| Abstract: | 3-Nitrobenzaldehyde was prepared from 3-nitrotoluene using AIBN as catalyst through bromination,hydration and oxidation. The yield and purity of 3-nitrobenzaldehyde was 30.4% and 99.2% under the optimum reaction conditions,n(3-nitrotoluene) ∶ n(hydrogen bromide) ∶ n(hydrogen peroxide) was 1 ∶ 3 ∶ 3,the bromination temperation was 65～75℃,the bromination time was 8～9 h,hydrolysis and oxidation time was 8 h. |
