Abstract

La 1-amino-2-bromo-4-hydroxyanthraquinone est préparée par hydroxylation de la 1-amino-2,4-dibromanthraquinone dans l'acide sulfurique concentré en présence d'acide borique à 110-130 degrés C et isolement du produit d'hydroxylation. On brome la 1-aminoanthraquinone dans l'acide sulfurique à 50-85 % entre 80 degrés C et 130 degrés C avec 1,5 à 2,1 molécules de brome par molécule de 1-aminoanthraquinone, on ajoute de l'oléum de manière à amener la concentration de l'acide sulfurique entre 96 % et 101 % (5 % SO3 ), on ajoute de l'acide borique et on hydroxyle le composé dibromé sans l'isoler. La 1-amino-2-bromo-4-hydroxyanthraquinone, très pure, est un produit intermédiaire dans la fabrication de colorants dispensables tels que la 1-amino-2-phénoxy-4-hydroxyanthraquinone et les 1-amino-2-alcoxy-4-hydroxyanthraquinones.
