Description

General description

4-Nitroaniline forms molecular adducts with 4-amino benzoic acid. It reacts with nitrite ion in hydrochloric acid medium to form 4-nitrophenyldiazonium chloride, which couples with naphth-1-ol in alkaline medium to give a purple azo dye. Photocatalytic degradation of 4-nitroaniline in the presence of TiO₂ suspensions in a batch and continuous annular reactor has been studied.

Application

4-Nitroaniline can be used to prepare:

• p

• -Phenylenediamine using various catalytic systems.
• Poly(4-nitroaniline) thin films for optoelectronic applications.
• An adduct with picric acid.
• A crystalline N-(4-nitrophenyl)-β-alanine by reacting with acrylic acid.

Product of chromogenic reactions.
