Method for manufacturing Nitrobenzol through adiabatic nitration

摘要

Procedure for continuous production of nitrobenzene, comprises adiabatic nitration of benzene with a mixture of sulfuric acid and nitric acid, where the sum of the concentration of the hardly soluble metal sulfate forming metal ions in the reaction zone is less than 900 mg/l, based on the volume of aqueous phase containing sulfuric acid.
