Application

Aniline may be used in the preparation of azobenzene.

Biochem/physiol Actions

The acute toxicity of aniline involves its activation in vivo to 4-hydroxyaniline and the formation of adducts with hemoglobin. In erythrocytes, this is associated with the release of iron and the accumulation of methemoglobin and the development of hemolytic anemia and inflammation of the spleen. Tumor formation is often observed in the spleen on prolonged administration.

General description

Aniline is an aromatic amine. It is a key industrial intermediate, widely employed for the preparation of dyes, rubber, resins and polymers. Complete vibrational assignements of aniline and its deuterated forms (aniline-NHD and aniline-ND2) have been reported.1 p-aminodiphenylamine (ADPA) has been reported to be formed as a major intermediate during the electropolymerizatrion of aniline. Its viscosity has been reported to be 3.1457cp at 30°C. Quantitative transformation of nitrobenzene to aniline has been carried out by employing functionalized plasmonic Au/TiO2 photocatalyst along with a Ag co-catalyst. Aniline can be prepared from nitrobenzene, via hydrogenation in the presence of Cu, Ni, Pt, Pd and Au (catalyst). It can also be prepared by photocatalytic reduction of nitrobenzene in the presence of WO3-Ag hybrid nanowires.
Material darkens in storage to reddish-brown with no loss in purity.

A functionalized plasmonic Au/TiO2 photocatalyst with an Ag co-catalyst was successfully prepared by the combination of two types of photodeposition methods, and it quantitatively converted nitrobenzene and 2-propanol to aniline and acetone under irradiation of visible light.
