Abstract: 2-Hydroxynaphthalene-3-carboxylic acid is prepared by the reaction of sodium- beta -naphtholate with carbon dioxide, extraction of the reaction mixture in the presence of water with benzene or a benzene derivative in a specific ratio and separation of the end product from the extracted mixture. The product is a starting material for the production of dyes and a coupling component in the manufacture of azo dyes.

Abstract: The preparation of 1-amino-2-carboxyanthraquinones I (I) (X denotes hydrogen, chlorine or bromine) by oxidation, under alkaline conditions, of a 1-aminoanthraquinone substituted in the 2-position by an oxidizable carbo-organic radical followed by acidification of the reaction mixture, wherein a 1-amino-2-acetylanthraquinone II (II) (Y denotes chlorine or bromine and n is equal to 0, 1 or 2) is reacted with a peroxide compound or oxygen as oxidizing agent.

Abstract: The patent describes an improved method for the synthesis of 1-amino-4-hydroxy- 2-(6'-hydroxy-hexyloxy)-anthraquinone (I). In III R = phenoxy, in (IV) R = Cl or Br, from 1-amino-4-hydroxy-2-halog-anthraquinone (IV), or 1-amino-4-hydroxy -2-phenoxy-anthraquinone (III), and 1,6-hexanediol with an alkali, in a polyethylene glycol or alcohol-ethylene-oxide adduct. If a halogeno-anthraquinone deriv. is used as starting material, a phenol must be added to the reaction-mixture so as to form the phenoxy-anthraquinone in situ. The method is improved by producing less of a by-product (II) previously found to have been problematic in use, because this by-product causes the dyestuff (I) to be weaker in colour, less heat fixable, less light-stable and causes the polyester in which it is the dye to be less ductile. By the method here described, the quality of by-product (II) in the final product can be reduced to 2% by wt. or below, by heating first to 125-135 deg. C then subsequently to 140-150 deg. C for 4-16 hrs.

Abstract: 1-Nitroanthraquinone-2-carboxylic acid of the formula I (I) is prepared by treating novel 2-substituted 1-nitroanthraquinones of the general formula II (II) where R is -CH=CH-R1 or -CH2-CHO, where R1 is C1-C5-dialkylamino or a cyclic 5- or 6-membered amine which may contain further hetero atoms, with oxidizing agents free of heavy metal.

Abstract: Disclosed is the preparation of quinophthalone derivatives of the general formula (I), in which the grouping A makes up unsubstituted or substituted heterocyclic aromatic rings and the grouping B makes up an unsubstituted or substituted aromatic ring, by reacting a methyl-substituted heterocyclic compound of the general formula (II), with an anhydride of an aromatic dicarboxylic acid of the general formula (III) or with the corresponding free dicarboxylic acid (IIIa) in the presence of an acid plus an organic solvent, using as the organic solvent an alkyl ester of benzoic acid.
