Abstract
Using o-nitroaniline as raw material, through acetylation, methylation, hydrolysis reactions, the target compound 2-methyl-6-nitroaniline was synthesized and characterized by IR, 1H NMR and 13C NMR. Both in the acetylation and methylation reaction, the influence of dosage of catalyst AlCl3, reaction temperature, reaction time, and adding rate of acetic anhydride in the former and adding rate of dimethyl sulfate in the latter were investigated. Under the optimal conditions, the yield of 2-methyl-6-nitroaniline was 93.9%.
