Abstract
Anthraquinone derivatives.-One mol of phenyldichlor-1,3,5-triazine is reacted with two mols of an aminoanthraquinone or a nuclear substitution product thereof at an elevated temperature and advantageously in the presence of an organic diluent and an acid-fixing agent. In examples one mol of phenyldichloro-1,3,5-triazine is condensed with two mols of 1-aminoanthraquinone (dyes yellow), 1-amino-5-benzoylaminoanthraquinone (dyes orange), 1-amino-4-benzoylaminoanthraquinone (dyes red) and 1-amino-4-methoxyanthraquinone (dyes orange). The hydrohalide salts of the aminoanthraquinones may be employed instead of the free bases. Specification 205,525, [Class 2 (iii), Dyes &c.], is referred to.
