Abstract

516,930. Dyes. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). July 13, 1938, No. 20778..Addition to 472,757. [Class 2 (iii)] Trianylmethane dyes capable of being chromed are made by condensing an N-acyl derivative of an aminotrimellitic acid or an anhydride or anhydro-compound thereof with an aromatic hydoxyl compound containing a reactive nuclear hydrogen atom and, in mposition to the' hydroxyl group, a substituted amino-group or a second hydroxyl group. The acyl derivatives used as parent materials may be made by reacting halogen-trimellitic acids with ammonia or p-toluene sulphamide and acylating the products with acid chlorides or anhydrides. Specified aromatic hydroxyl compounds are m-dimethylaminophenol, m-dimethylamino-p-cresol and the corresponding diethyl, dipropyl, dibutyl and di-isobutyl derivatives, similar hydroxyl compounds containing different substituents at the 'nitrogen, e.g., the methylethylamino compounds, the corresponding mono-substituted derivatives, 3-hydroxydiphenylamine and its derivatives, m-piperidylphenol (parent Specification, Ex. 9), N-(3-hydroxyphenyl)-morpholine (parent Specification, Ex. 20), m-disulphethylamino-phenol, 3-ethylsulphethylamino-4-methylphenol, mmethylsulphethylaminophenol, m-dihydroxyethylaminophenol, resorcinol, halogen- and nitro-resorcinols, resorcylic acid, pyrogallol and 1:3-dihydroxynaphthalene. The condensation may be effected by heating the substances together, or zinc chloride may be used as a condensing agent. The products, after splitting off the acyl group, dye animal fabrics in an acid bath clear orange, yellow to bluish-red tints ; they may also be used for chrome printing on cotton, artificial silk &c. The dyes may also be converted into complex chromium compounds in substance. The preparation of dyes from anhydro-5-acetylaminotrimellitic acid and mdiethylaminophenol, m-ethylaminophenol, methylamino-p-cresol, and resorcinol is described in examples. Specification 477,605 is referred to.
