Process for the preparation of anthraquinone imides |
| abstract |
In the preparation of anthraquinone imides by condensing a vattable anthraquinone compound which contains at least one primary amino group with an aromatic halogen compound, in an organic solvent and at elevated temperature, it is advantageous first to heat the organic solvent to the reaction temperature and then, at this temperature, to add the educts to the solvent. |
