Abstract

On effectue l'oxydation du o-benzyl-toluol avec de l'acide nitrique, jusqu'à ralentissement de la formation des oxydes d'azote, au moyen d'un acide nitrique à 25 à 50 % en poids, sous pression atmosphérique, à une température comprise entre environ 80 et 110 degrés C, en présence des catalyseurs d'oxydation connus, et que l'on continue l'oxydation du produit d'oxydation fluide jusqu'à la fin de la formation des oxydes d'azote, au moyen d'acide nitrique à 8 à 15 % en poids sous une pression comprise entre environ 10 et 30 bars à une température comprise entre environ 150 et 180 degrés C, l'acide brut o-benzoyl-bensoïque obtenu est estérifié, puis le méthylester est transformé en anthraquinone par de l'acide sulfurique concentré à une température d'environ 150 degrés C.The oxidation of o-benzyl-toluol is carried out with nitric acid, until the formation of nitrogen oxides is slowed down, by means of a nitric acid at 25 to 50% by weight, at atmospheric pressure, at a temperature between about 80 and 110 degrees C, in the presence of known oxidation catalysts, and that the oxidation of the fluid oxidation product is continued until the end of the formation of nitrogen oxides, by means of 8 to 15% by weight nitric acid under a pressure of between about 10 and 30 bars at a temperature of between about 150 and 180 degrees C, the crude o-benzoyl-bensoic acid obtained is esterified, then the methyl ester is converted into anthraquinone by concentrated sulfuric acid at a temperature of about 150 degrees C.
