    510,010. Dyes. GROVES, W. W. (I.G. Farbenindustrie Akt.-Ges.). Jan. 25, 1938, No. 2382. [Classes 2 (iii) and 15 (ii)] Products of the formula where X is'OH or NHR, where NHR is the radical of a primary amine, are made by reacting leuco-5.6.7.8-tetrahydroquinizarin with a primary amine or mixture of amines and oxidizing the leuco-compound so obtained. Also according to the invention, leuco-5,6,7,8-tetrahydroquinizarin is made by hydrogenating a quinizarin ether in 'presence of a metal catalyst to give a hexahydroquinizarin ether, which is saponified, e.g., with sulphuric or phosphoric acid. The products of the above formula may be sulphonated and dye wool or acetate artificial silk blue to green tints. Amines specified include benzylamine and amines containing sulpho groups. The reaction is preferably conducted in a diluent, such as alcohol or excess amine, below 200‹C., and sometimes in presence of boric acid, followed by oxidation with air sometimes in presence of piperidine or ferric chloride, e.g., in glacial acetic acid. In examples, leuco-5,6,7,8-tetrahydroquinizarin is reacted with the following amines, followed by oxidation and in some cases sulphonation of the products : (1) p-toluidine, (2) 4-aminodiphenyl, (3) 4- cyclohexylaniline, (4) ethylamine or methylamine, (5) hydroxyethylamine, (6) cyclohexylamine in about equimolecular proportion, or (7) in excess. (8) mesidine, (9) 2-amino-1.2.3.4- tetrahydronaphthalene, the diamino body being obtained in every case except (6), and with (10) a mixture of ethylamine and hydroxyethylamine to give 1-ethylamino-4-#-hydroxyethylamino - 5.6.7.8 - tetrahydroanthraquinone, (11) p-n-butoxyaniline, '(12) p-n-butylaniline, (13) a mixture of methylamine and hydroxyethylamine to give 1-methylamino-4-hydroxyethylamino - 5,7.6.8 - tetrahydroanthraquinone, (14) p-tert.-butylaniline. In further examples, quinizarin dimethyl or diethyl ether is hydrogenated under pressure in presence of a nickel catalyst, followed by saponification with concentrated sulphuric acid.
