| titleOfInvention | Method for producing nitrobenzene by adiabatic nitration |
| abstract | The invention relates to a continuously operated adiabatic process for producing nitrobenzene by the nitration of benzene with nitric acid and sulfuric acid. According to said method, the diluted sulfuric acid obtained after successful nitration of the untreated nitrobenzene and separation of the latter from the aqueous phase, is concentrated in order to be re-used in the nitration process, and once concentrated is supplied with an oxidant for at least one minute, before being brought into contact again with fresh nitric acid, such that the concentration of the oxidant achieves between 10 ppm and 5,000 ppm in relation to the total mass of the concentrated sulfuric acid that is to be re-used in the nitration process. |
