Abstract

L'invention concerne un procédé d'obtention d'anthraquinone purifiée à partir d'anthraquinone brute. L'anthraquinone brute est traitée par un composé oxygéné des éléments du premier et/ou du second groupe de la Classification Périodique des Eléments, à haute temperature, éventuellement en présence d'un solvant, après quoi on effectue une sublimation ou une évaporation pour récupérer l'anthraquinone pure. Pureté > 99 %.
