- Ring Opening Reactions of 6H-Anthraisoxazol-6-ones and Related Compounds
-
Nucleophilic attack of anthraisoxazol-6-ones, and of anthraisoxazole by various sulfoxides, triphenyl phosphine, and aliphatic or aromatic phosphites proceeded with cleavage of the nitrogen-oxygen bond of the isoxazole ring.This method provided ready access to substituted anthraquinones bearing sulfoximido-, triphenylphosphazo-, and dialkyl(aryl)phosphoramidic groups attached to the 1- and the 1,5-positions of the anthraquinone system.The structures of the newly synthesized anthraquinone derivatives were supported by analytical and spectral data. 1 -S,S-dimethyl-N-(5-benzamidoanthraquinon-1-yl)sulfoximide yielded in 90percent sulfuric acid the 1-amino-5-sulfoximido anthraquinone without hydrolyzing the sulfoximido group.

- Anthraquinone derivatives
-
Anthraquinone derivatives of the formula STR1 or of the tautomeric formula STR2 in which A denotes an anthraquinone radical which is free from sulphonic acid groups and is optionally further substituted and which preferably consists of at most 5 fused rings, m denotes an integer, preferably 1 or 2, and R1 denotes a hydroxyl group or a radical of the formula STR3 wherein R2 represents a substituent and n represents 0, 1, 2, 3 or 4, processes for their preparation, their use for pigmenting organic macromolecular substances and the material pigmented in this manner.

- Process for the preparation of 1-acylamino-5(8)-chloroanthraquinones
-
The invention relates to a novel process for the preparation of 1-acylamino-5(8)-chloroanthraquinones, which are starting materials for the preparation of vat dyes. It is characterized in that 1,5(8)-dichloroanthraquinones is reacted with ammonia at temperatures of 190° to 240° C., the amino groups in the reaction mixture are completely acylated and the more sparingly soluble diacylaminoanthraquinone is separated off from the more readily soluble monoacylaminochloroanthraquinone. The new process yields reaction products which are purer and cheaper than those which are obtained by conventional methods. Moreover there are smaller waste water problems.

- Process for the production of amino-anthraquinone
-
The present invention concerns a novel improvement in the catalytic hydrogenation of nitroanthraquinones to produce aminoanthraquinones, comprising over-hydrogenating the resulting aminoanthraquinone to the corresponding nuclear hydrogenated aminoanthraquinone and, after removal of the aminoanthraquinone, oxidising the remaining nuclear-hydrogenated aminoanthraquinone to aminoanthraquinone. Aminoanthraquinones are useful as intermediates in the production of anthraquinone dyestuffs.
