Abstract

Mixtures comprising 1,5- and 1,8-dihydroxy-a -nitro-a -arylamino-anthraquinonones are obtained by reacting a mixture, consisting substantially of dinitroanthraquinones and containing at least 40 per cent of 1.5-dihydroxy-4,8-dinitroanthraquinone and 1,8-dihydroxy-4,5-dinitroanthraquinone, taken together, with an aromatic amine of the benzene series free from water-solubilizing groups at 100-150 DEG C. in absence of more than 5 per cent water calculated on the reaction mixture, and substantially in the absence of an organic solvent. The mixture used as starting material may be obtained by dinitrating anthraquinone, exchanging the nitro groups for alkoxy or phenoxy, again dinitrating, and then hydrolysing the alkoxy or phenoxy groups; after each nitration by-products which are obtained in addition to the isomers containing nitro groups in different rings may be removed by fractional precipitation by adding water to the sulphuric acid solution of the mixture. The amines employed may contain halogen or alkyl, alkoxy, or oxyalkyl substituents up to 4 carbon atoms. The products may be used as pigments, or for dyeing or printing cellulose esters, nylon, polyurethanes, polyvinyl compounds, and polyesters. In examples, mixtures as described above are heated with: (1) aniline; (2) m-aminobenzyl alcohol; (3) p-aminophenylethyl alcohol; (4) a crude mixture of xylidines; (5) m-toluidine; (6) p-anisidine. A further example describes the acid-pasting of a product derived from aniline and its use to dye cellulose acetate blue shades. Specifications 420,591, [Group IV], 612,009 and 646,459 are referred to.
