Mononitrotoluenes can be prepared by intensively or simultaneously successively mixing toluene, nitric acid, sulfuric acid and water together in their total amount and, in the case of continuous production, redispersing at least twice, for which purpose a mixing energy per volume of the reactor of 1 to 40 watts per liter of the entire reaction mixture , preferably 3 to 30 W / I, is used, and the backmixing is largely suppressed when the process is carried out continuously. Adiabatic reaction conditions are observed. |
