Abstract

L'invention a pour objet un procédé d'obtention de dinitro-1,5 anthraquinone de haute pureté à partir de mélanges bruts de dinitro-anthraquinones. On traite un tel mélange à une température allant de 150 à 200 degrés C au moyen d'un ester de point d'ébullition supérieur à 150 degrés C dérivé d'un alcool aliphatique contenant 1 à 4 atomes de carbone et d'un acide mono- ou dicarboxylique ou d'acide phosphorique, puis, après refroidissement éventuel sans descendre en-dessous de 150 degrés C, on sépare l'insoluble constitué essentiellement par la dinitro-1,5 anthraquinone.
