Abstract

L'oxydation de o-benzyl-toluol par l'air en solution d'acide acétique est effectuée avec addition de la quantité d'anhydre acétique nécessaire à la combinaison de l'eau de réaction, l'acide o-benzoyl-benzoïque brut obtenu est estérifié, après quoi le méthylester est transformé en anthraquinone par chauffage avec de l'acide sulfurique concentré à une température d'environ 150 degrés C.
