Zusammenfassung:	The present invention relates to a method for removing impurities from nitrated crude products obtained during the nitration of nitratable aromatic compounds, after removal of the final nitrating acid, by treatment with a washing medium, and also to a plant or apparatus suitable for implementing this method. Further provided by the invention is a production plant for the nitration of nitratable aromatic compounds, with subsequent purification of the nitrated products. L'invention concerne un procédé et dispositif permettant d'évacuer des impuretés de produits bruts nitrés résultant de la nitration de composés aromatiques nitrables après séparation des acides nitriques terminaux, par traitement au moyen d'un agent de nettoyage, ainsi qu'une installation ou un dispositif aptes à la réalisation de ce procédé. L'invention porte également sur une installation de production destinée à la nitration de composés aromatiques nitrables avec purification subséquente des produits nitrés.
