FIELD: chemical industry. SUBSTANCE: 2-bromo-4,6-dinitroaniline is synthesized from 1,2-dibromo-3,5-dinitrobenzene obtained by simultaneous nitration and bromination of bromobenzene or nitrobromobenzene with brominating agent taken from the order: bromine, alkaline metal bromides, ammonium bromide in the presence of sulfuric acid and nitric acid or nitrate using ammonolysis in aqueous-ammoniacal medium in the presence of disperser. EFFECT: improved method of synthesis.
