Abstract
Vat dyestuffs are manufactured by condensing an a :a <1>-diaminodiphthaloylcarbazole with one molecular proportion of a Bz1-halogenbenzanthrone and treating the condensation product formed with an alkaline condensing agent and an acylating agent, or by condensing an a - acylamino - a <1> - aminodiphthaloylcarbazole with a Bz1-halogenbenzanthrone and treating the condensation product formed with an alkaline condensing agent free from hydroxyl groups, or by employing in the latter process an alkaline condensing agent containing a hydroxyl group, whereby the acylamino group is saponified, and subsequently acylating the free amino group. The products dye cotton brownish to olive to greenish shades. In examples: (1) Bz1-bromobenzanthrone is condensed with 5 - amino - 5<1> - benzoylaminodiphthaloylcarbazole, or with the 5 : 5<1>-diamino compound with subsequent benzoylation, and the product is heated with a solution of sodium anilide in aniline; (2) 5 : 5<1>-diaminodiphthaloyl-carbazole is condensed with Bz1-bromobenzanthrone and the product is fused with alcoholic caustic potish and then treated with benzoyl chloride or a halogen derivative thereof in o - dichlorbenzene; the product may be sulphonated by dissolving it in sulphuric acid and subsequently precipitating it; (3) the condensation product of (2) is boiled with acetic anhydride; the product may be treated with sulphuric acid as in (2); (4) the condensation product of (2) is refluxed in o-dichlorbenzene with anthraquinone-2-carboxylic acid chloride or its 1-nitro derivative; (5) 4-benzoylamino - 4<1> - aminodiphthaloylcarbazole is condensed with Bz1-bromobenzanthrone and the product is fused with alcoholic caustic potash and then treated with benzoyl chloride or benzoic anhydride in o-dichlorbenzene; the product may be treated with sulphuric acid as in (2); (6) 4 : 5<1>-diaminodiphthaloylcarbazole is condensed with Bz1 - bromobenzanthrone and the product is fused with alcoholic caustic potash and then benzoylated as in (2). Specification 347,100 is referred to.
