| titleOfInvention | Production of aminoanthraquinones from nitroanthraquinones |
| abstract | 1477038 Aminoanthraquinones from nitroanthraquinones BASF AG 30 Aug 1974 [1 Sept 1973] 37931/74 Heading C4P A process for the production of an aminoanthraquinone (or aminobenzanthrone) is claimed, wherein the corresponding nitro compound is reduced in an aqueous solution containing from 0À5 to 50% by weight of an alkaline-reacting agent with at least the stoichiometrically necessary amount of a hydrazine at a temperature of from 25‹ C. to the boiling temperatures of the reaction mixture. Hydrazine, methylhydrazine, N,N-dimethylhydrazine or phenylhydrazine may be used, and as alkaline reagent NaOH, KOH, Na 2 CO 3 or K 2 CO 3 or mixtures may be employed. Examples describe the preparation of: a mixture of 1,5-diamino-4,8-dihydroxy- and 1,8- diamino - 4,5 - dihydroxyanthraquinones; 1- aminoanthraquinone; 2 - carboxy -, 5 - chloro-, 2 - and 2 - ethyl - 1 - aminoanthraquinone; 1,4 - dichloro - 5 - amino - anthraquinone; 1,2- dihydroxy - 3 - aminoanthraquinone; a mixture of 1,5- and 1,8-diaminoanthraquinones; 1,5 - diamino - 4,8 - dihydroxyanthraquinone; 1,4 - diaminoanthraquinone - 2 - carboxylic acid; 1 - amino - 2 - methylanthraquinone; 1- amino - 5 - [4<SP>1 </SP>- chlorophenylamino] - 4,8 - dihydroxyanthraquinone; Bz - 1 - aminobenzanthrone; Bz - 1,6 - diaminobenzanthrone; and 1-amino-2-hydroxyanthraquinone. In addition the use of: 1,5-dinitroanthraquinone; 1,8 - dinitroanthraquinone; 1 - nitro- 4 - hydroxyanthraquinone; 1 - nitro - 4,5,8- trichloroanthraquinone; 5 - nitro - 1 - aminoanthraquinone; 1,5 - dinitro - 4,8 - dichloroanthraquinone; 1,5 - dinitro - 4,8 - dimethoxyanthraquinone; 1,8 - dinitro - 4,5 - dimethoxyanthraquinone; 1 - nitro - 5 - phenylamino- 4,8 - dihydroxyanthraquinone; 1 - nitro - 5- phenylaminoanthraquinone; 1,4 - diamino - 5- nitroanthraquinone; 2 - nitroanthraquinone; 1,6 - dinitroanthraquinone; 2,7 - dinitroanthraquinone and Bz - 1 - bromo - 6 - nitrobenzanthrone in the preparation of the corresponding amino compounds is also claimed. |
