| titleOfInvention | Process for the manufacture of 1,4-diamino-5-nitroanthraquinone |
| abstract | A process for the manufacture of 1,4-diamino-5-nitroanthraquinone from 1,4-diaminoanthraquinone by nitration with mixed nitric and sulphuric acid, before which nitration a masking of the two amino groups to form 1,9-4,10-anthraquinone disulphonimide takes place, this intermediate being in turn split by hydrolysis after the nitration, which process comprises carrying out the masking of the 1,4-diaminoanthraquinone to form the 1,9-4,10-anthraquinone-disulphonimide with liquid sulphur trioxide and carrying out the entire nitration process by using liquid solvents which are inert towards the reactants. |
