| titleOfInvention | Process for the manufacture of aminohydroxyanthraquinones |
| abstract | The invention relates to a process for the manufacture of an aminohydroxyanthraquinone of the formula ##STR1## wherein both of X are hydrogen or one X is --NH 2 and the other is --OH and Z is hydrogen, C 1 -C 4 alkyl or carboxyl, with the proviso that, if Z is C 1 -C 4 alkyl or carboxyl, both of X must be hydrogen, which process comprises reacting a nitroanthraquinone of the formula ##STR2## wherein both of Y are hydrogen or one Y is --NO 2 and the other is hydrogen and Z is as defined for formula (1), with the proviso that, if Z is C 1 -C 4 alkyl or carboxyl, both of Y must be hydrogen, in an aprotic dipolar solvent, with an alkali metal azide or alkaline earth metal azide, in the temperature range between 0° and 30° C. The reaction products are disperse dyes or intermediates for obtaining vat dyes and disperse dyes. |
