Abstract:

A process for producing aromatic nitro compound which comprises nitrating an aromatic compound by blowing oxygen or air containing a nitrogen oxide and ozone into a solution or suspension thereof in an organohalogen solvent. The use of the oxygen or air containing a nitrogen oxide and ozone as the nitrating agent makes it possible to produce an aromatic nitro compound under mild conditions without using any inorganic acid and to remove various troubles accompanying the use of an inorganic acid in the conventional production process.
