Abstract

13,612. Bloxam, A. G., [Chemische Fabrik Griesheim Elektron]. June 10. #-Aziminoanthracene dyes are obtained by oxidizing the aminoazo dyes obtained by combining 2-diazoanthraquinone with 2-aminoanthracene or 2:6-diaminoanthracene. Further oxidization converts the anthracene residue into the anthraquinone residue. These products dye yellow shades from a vat. Brown to violetbrown vat dyes are obtained by nitrating and then reducing the above products. According to examples, the monoazo dye from 2-diazoanthraquinone and 2-aminoanthracene, and the primary disazo dye from two molecular parts of 2-diazoanthraquinone and 2:6-diaminoanthracene, are oxidized by means of bichromate or hypochlorite; mono-and di-nitro and -amino derivatives of the first-mentioned products are also described.
