Abstract: A process for the continuous preparation of phthalimide by reacting phthalic anhydride with ammonia in about the stoichiometric ratio, in a mixing apparatus and subsequently in a reaction tube at a particular flow velocity and a particular temperature. The phthalimide obtainable by the process of the invention is a valuable starting material for the preparation of dyes, pesticides and pigments, especially copper phthalocyanines.

Abstract: Anthranilic acid is manufactured continuously by reacting an alkali metal phthalamate and/or phthalimidate with an alkali metal hypohalite in a reaction tube, the resulting anthranilic acid being treated, during or after the reaction, with reducing agents in two steps, the reducing agents employed in the two steps being different from one another, and an alkali metal dithionite or alkali metal formaldehyde-sulfoxylate being used as the reducing agent in the second treatment step. The product is a starting material for the preparation of dyes, crop protection agents and scents.

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.
