The possibility of N-nitration of primary aromatic amines containing SO3H and COOH groups by polynitro compounds C(NO2)4, (O2N)3CC(NO2)3, CH3C(NO2)3, C(NO2)3CH2CH2CN, and C(NO2)3CH2CH2COOCH3 and by polynitroxy compounds C(CH2ONO2)4 and HOCH2C(CH2ONO2)3 was investigated.In the presence of alkaline agents tetranitromethane, hexanitroethane, and pentaerythritol tetranitrate nitrate para- and meta-substituted aromatic amines with the formation of the corresponding nitroamine salts.Ortho-substituted amines do not enter into this reaction.

The dependence of the yields of the salts of N-nitrosulfanilic acid and nitroform and the amount of reacted sodium hydroxide on the temperature and the pH of the medium in the reaction of sodium sulfanilate with tetranitromethane was investigated.Nitration mostly occurs at pH values of more than 12; at lower pH values decomposition of the tetranitromethane predominates.At pH values of not less than 10 the process is described satisfactorily by three reactions, i.e., nitration of the sulfanilate salt and two reactions involving decomposition of the tetranitromethane.
