| 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. |
| Application: | Product of chromogenic reactions. |
| 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. |
