| abstract | Cyanuric chloride or its substitution products are condensed with aminoanthraquinones or substitution products thereof containing at least one replaceable hydrogen atom attached to the nitrogen atom in the presence of aromatic hydroxy compounds, but in the absence of acid-binding agents. Suitable aromatic hydroxy compounds are phenol, o- and p-chlorophenol, cresols, and a -naphthol, and while they are preferably employed in sufficient quantity alone, they may be used together with an organic solvent such as nitrobenzene, or o-dichlorobenzene. The components are dissolved in approximately theoretical proportions in the hydroxy body, and condensation preferably effected at temperatures of 80-150 DEG C. In examples, (1) a -aminoanthraquinone (3 mols.) is condensed with cyanuric chloride (1 mol.) in presence of phenol, o-chlorphenol, p-chlorphenol, or a -naphthol: (2) b -aminoanthraquinone (3 mols.) is condensed with cyanuric chloride (1 mol.) in presence of phenol: (3) a -aminoanthraquinone (1 mol.) and b -aminoaminoanthraquinone (2 mols.) are condensed with cyanuric chloride (1 mol.) in presence of p-chlorphenol: (4) 1-amino-4-benzoylaminoanthraquinone (3 mols.) is condensed with cyanuric chloride (1 mol.) in presence of p-chlorphenol: (5) a -aminoanthraquinone (2 mols.) is condensed with phenyldichloro-1.3.5-triazine (1 mol.) in presence of phenol: (6) 4-amino-1.1<1>-dianthraquinonylamine (2 mols.) is condensed with phenyldichlor-1.3.5-triazine (1 mol.) in presence of phenol; both chlorine atoms are replaced in contradistinction to the product obtained when using nitrobenzene as solvent: (7) a -aminoanthraquinone (2 mols.) is condensed with methyldichlor-1.3.5-triazine (1 mol.) in presence of phenol: (8) Bz2-4-dichloro-4-aminoanthraquinone-1.2-benzacridone (2 mols.) is condensed with methyldichloro-1.3.5-triazine (1 mol.) in presence of phenol: (9) a -aminoanthraquinone (2 mols.) is condensed with ethyldichlor-1.3.5-triazine (1 mol.) in presence of p-nitrophenol: (10) 1-amino-4-benzoylaminoanthraquinone (2 mols.) is condensed with cyclohexyldichloro-1.3.5-triazine (1 mol.) (prepared by reacting upon cyanuric chloride with cyclohexyl magnesium bromide) in presence of phenol: (11) 1-amino-5-benzoylaminoanthraquinone (2 mols.) is condensed with benzyldichloro-1.3.5-triazine (1 mol.) (prepared by reacting upon cyanuric chloride with benzyl magnesium bromide) in presence of phenol. Specifications 205,525, 231,688, 234,086, 237,872, 278,728, [all in Class 2 (iii), Dyes &c.], and 350,575 are referred to. |
