FIELD: organic chemistry, quantitative determination of blood, immunoferment analysis. SUBSTANCE: 2,6-dimethylaniline is oxidized by hydrogen peroxide to prepare 2,6-dimethylnitrobenzene being intermediate product. Said compound is then affected by reduction with the help of zinc powder which takes place in the presence of ammonium chloride. The process is followed by treatment with sulfuric acid. EFFECT: improved efficiency.
