Abstract
297,133. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). June J1, 1927. Anthraquinone vat dyes.-Aluminium chloride fusions of anthraquinone derivatives for the purpose of preparing vat dyes are carried out in presence of an aromatic tertiary base. The base, such as pyridine, quinoline, or dimethylaniline, and the aluminium chloride are preferably mixed first, when a compound, soluble in excess of pyridine, is produced. In examples, #-aminoanthraquinone is condensed to flavanthrone and 4- benzoyl-amino-1: 1<1>-dianthraquinonylamine, 1 : 2<1>-dianthraquinonylamine, 4-a-anthraquinonylamino-methylanthrapyridone, and 1 : 4-di(a-anthraquinonylamino)-anthraquinone are, condensed to vat dyestuffs; the last-mentioned product is identical with that obtained by purification with sulphonic acid of the product of potash fusion of the parent material. The processes claimed in Specifications 278,771 and 288,291, and the condensation of 1: 1<1>-dianthraquinonylamine, are excluded.
