Abstract

337,741. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 4, 1929. Benzanthrone derivatives. - Anthraquinonylaminobenzanthrones containing two or more anthraquinonylamino groups, one of which is in the Bz1-position, are converted into vat dyes by treating them with alkaline condensing agents. The products may be subsequently treated with acid condensing agents if desired. In examples, (1) di(1<1>-anthraquinonyl) - 6: Bz1-diaminobenzanthrone, obtained by condensing 6 : Bz1-dihalogenbenzanthrone (1 mol.) with 1-aminoanthraquinone (2 mols.), is fused with alcoholic potash; the product dyes cotton in olive brown shades, (2) the product of example 1 is converted to a dyestuff dyeing green shades by heating it with concentrated sulphuric acid, (3) the condensation product from 6: Bz1<1>-dihalogenbenzanthrone (1 mol.) and 1: 6-diaminoanthraquinone (2 mols.) is fused with caustic potash and methylalcohol; the product dyes in olive brown shades, (4) di(1<1>- anthraquinonyl) - 7: Bz1 - diaminobenzanthrone, obtained by condensing Bz1-brom-7-chlorbenzanthrone (made by brominating 7-chlorbenzanthrone in nitrobenzene) with 1-aminoanthraquinone (2 mols.) is fused with caustic potash and methyl alcohol; the product dyes in dark brown shades, (5) tri(1<1>-anthraquinonyl)-triaminobenzanthrone, obtained by condensing tribromobenzanthrone (made by brominating benzanthrone in chlorsulphonic acid) with 1-aminoanthraquinone (3 mols.), is fused with alcoholic potash; the product dyes in fast brown shades, (6) the condensation product from 6: Bz1-dibrombenzanthrone (1 mol.) and I-amino-4-anilidoanthraquinone (2 mols.) is fused with alcoholic potash; the product dyes olive-grey shades, (7) the product of example 6 is fused with sodium and aluminium chlorides, and (8) the condensation, product from 6: Bz1-dibrombenzanthrone (1 mol.) and 1-amino- 5-benzoylaminoanthraquinone (2 mols.) is heated with sodium anilide and aniline, the product dyes olive brown shades; similar products are obtained from the condensation products of 6 : Bz1-dibrombenzanthrone (1 mol.) and 1-amino-4-benzoylaminoanthraquinone (2 mols.) or 1-amino-5- benzoylaminoanthraquinone (1 mol.) and 1-aminoanthraquinone or another aminoanthraquinone derivative (1 mol.). Specification 306,874 is referred to.
