HOE 90/F 390 Process for the continuous nitration of nitratable aromatic compounds A process for the continuous nitration of a nitratable aromatic compound, which forms an azeotrope with water, by treatment with nitric acid in the presence of nitrating acids, which comprises carrying out the reaction using a molar ratio of nitric acid to the aromatic compound of at least 1.1, the temperature and the pressure being coordinated with one another in such a way that the reaction mixture boils, recycling the nitrating acid in the circulation without further intermediate treatment, extracting the product mixture with water and recycling the eluate, to return nitrating acid. to the reaction.
