Production

4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene using oxygen or dichromate as oxidants.

Alternatively, it has been prepared by nitration of polystyrene followed by oxidation of the alkyl substituent. This method proceeds with improved para/ortho selectivity owing to the steric protection of the ortho positions by the polymer backbone.

Safety

This compound has a rat LD50 of 1960 mg/kg.
