Abstract
2-Nitro-4-methylsulfonyl benzoic acid was synthesized from 2-nitro-4-methylsulfonyl toluene by air-nitric acid combined oxidation.Optimized conditions were got by investigating the material ratio,reaction temperature,reaction time,dropping speed of nitric acid,aeration velocity.Enlarged experiment was researched under the optimum reaction condition,which showed that the average yield and the purity of product could reach to 85% and 97.1% respectively.
