Abstract

La presente invención se refiere a procedimiento para la elaboración de una mezcla de 1-amino-2cloro-4-hidroxiantraquinona y 1-amino-2-bromo-4-hidroxiantraquinona con una alta proporción de 1-amino-2-cloro-4-hidroxiantraquinona, caracterizado por clorura 1-aminoantraquinona en un disolvente orgánico inerte hasta haber de 60 a 90 por ciento 1-amino-2.4-dicloroan traquinona, por bromurar la mezcla reaccionada menos del 2 porciento del producto primario y del producto monohalogenado, por transformar los productos obtenidos finalmente con ácido sulfúrico concentrado o fumante en 1-amino-2-cloro-4-hidroxiantraquinona y 1-amino-2-bromo-4-hidroxiantraquinona, y por aislar la mezcla obtenida uso de la mezcla conforme a la reinvindicación 12, a lo ya descrito para la fabricación de colorantes.
