Reaktionsschritte
In the manufacture of nitroaromatics, particularly dinitrotoluene, the aromatic compound is contacted under liquid phase conditions with the mixture of concentrated nitric acid and sulfuric acid. In the production of nitroaromatics and particularly dinitrated products either dinitrobenzene or dinitrotoluene, some by-product nitrophenolic material is produced. This nitrophenolic material usually is in the form of nitrocresols either dinitro or trinitrocresol and picric acid. It is this product which is removed from the crude reaction product from the nitration reactors without creating an environmentally unacceptable stream.
