Abstract

334,240. Johnson, J. Y., (I. G. Farbeninditstrie Akt.-Ges.). May 30, 1929. Anthraquinone acridones. -Vat dyestuffs are prepared by condensing Bz 3: 5-dichloro-4-chloranthraquinone-2 : 1(N)-acridone with amides of aromatic carboxylic or sulphonic acids, and the products saponified if desired. The above acridone-amide condensation products may be obtained more advantageously in some cases by recondensing the saponified products with an aromatic acid chloride. Condensation is preferably carried out in a diluting or suspending medium and in presence of acid-fixing agents; condensing catalysts such as copper or its compounds may also be added. In examples Bz3.5-dichloro-4- chloroanthraquinone-2.1-(N)-acridone (prepared by treating with anthraquinone-2 : 1(N)-acridone suspended in nitrobenzene with sulphuryl chloride in presence of iodinechloride) is condensed (1) with p-toluenesulphonamide and the product saponified by concentrated sulphuric acid at 80‹ C; (2) with benzamide and the product saponified as above; and (3) with either above amide and saponified and the product condensed with 1- chloranthraquinone-2-carboxylic acid chloride. The products dye cotton violet to blue shades.
