Abstract

L'invention a pour objet un procédé d'obtention d' alpha , alpha '-dinitro-anthraquinones de haute pureté à partir de mélanges bruts issus de la dinitration de l'anthraquinone. On met en contact un tel mélange avec un ester de point d'ébullition supérieur à 120 degrés C dérive d'acide mono- ou dicarboxylique ou d'acide phosphorique, à une température comprise entre 20 et 200 degrés C, puis, après refroidissement éventuel, on sépare l'insoluble constitué essentiellement par les alpha , alpha '-dinitro-anthraquinones.
