A process for producing a mixture of isomers of dinitronaphthalene by nitration of nitronaphthalene, in which nitronaphthalene, optionally in an inert organic solvent, is reacted with 1 to 20 times the equivalent quantity, based on the quantity of nitronaphthalene, of 50% to 100% nitric acid in the presence of a solid, perfluorinated, strongly acidic ion exchanger. |
