Beschreibung
Zusammenfassung:	Selectively introduction of a nitro group into monocyclic aromatic compounds uses a mixture of nitric acid and sulphuric acid. A central, moving stream of the acid (A) is formed, and the aromatic compound (B) is introduced so that (A) is surrounded by (B). Also claimed is a mixing device for this method. The device has a mixing tube (2) with an inner tube (3). In the intermediate hollow region (4) between these tubes there is an inlet (5) for (B) and another inlet (6) for (A). The ratio of inner tube diameter to mixing tube diameter is 0.7 - 0.98.
