| abstract | 17,123. Farbwerke vorm. Meister, Lucius, & Br³ning. July 25, 1912, [Convention date]. p-Nitro-phenylurea derivatives are prepared by treating p-nitrophenylurea chloride with a primary or secondary amine or a substitution product thereof in the presence or absence of an agent neutralizing hydrochloric acid. p-p<1>- Dinitrodiphenylurea, which is a colour-lake, may be also prepared by the action of one molecular proportion of phosgene upon two molecular proportions of p-nitraniline, initially at a low, and afterwards at a raised, temperature. Suitable amines for use as described above are aniline, toluidine, naphthylamine, aminoanthraquinones, halogennitroamines, sulphanilic acid and its isomers, homologues, &c., naphthylamine and aminonaphthol sulphonic acids, diaminostilbenedisulphonic acid, benzidine sulphonic acid, &c. p-Nitrophenylureachloride is obtained by the action of phosgene upon p-nitraniline. |
