Abstract: An improvement in the process for the production of 1-amino-4-nitroanthraquinone-2-carboxylic acid from 1-aminoanthraquinone-2-carboxylic acid by reaction with formaldehyde in concentrated sulfuric acid and nitration of the reaction product into 1,2-dihydro-6-nitro-7,8-diphthaloyl-3,1,4H-benzoxazone-4 followed by hydrolysis of the same. The improvement consists in precipitating the benzoxazone derivative by adding a precipitant, hydrolyzing the isolated benzoxazone derivative in aqueous solution and precipitating the 1-amino-4-nitro-anthraquinone-2-carboxylic acid from the alkaline solution by acidification. 1-amino-4-nitroanthraquinone-2-carboxylic acid is obtained in a purity of 95 percent by weight or more.

Abstract: Production of 1-amino-4-hydroxyanthraquinones, which can be substituted in the 2- and 3-positions by carboxylic acid, carboxylic ester or alkyl groups or chlorine or bromine, by heating 3'-nitrobenzoyl-benzoic acids, which can be substituted in the 4'- and 5'-positions, in sulfuric acid or oleum in the presence of boric acid, boric acid esters, boron trihalides or their complex compounds to temperatures between about 120 DEG and 200 DEG C. The reaction products are dyes or intermediates for valuable disperse dyes.
