Chemical Properties:
Aniline is the simplest primary aromatic amine and a
compound formed by the substitution of a hydrogen atom in the benzene molecule
with an amino group. It is colorless oil like flammable liquid with strong
odor. When heated to 370 C, it is slightly soluble in water and soluble in
ethanol, ether, chloroform and other organic solvents. It becomes brown in the
air or under the sun. It can be distilled by steam. A small amount of zinc
powder is added to prevent oxidation when it is distilled. The purified aniline
can be added 10 ~ 15ppm NaBH4 to prevent oxidation deterioration. The solution
of aniline is alkaline.
It is easy to produce salt when it reacts with acid. The hydrogen atoms on its
amino groups can be substituted by alkyl or acyl groups to produce second or
third grade aniline and acyl aniline. When substitution reaction occurs, the
products of ortho and para substituted products are mainly produced. It reacts
with nitrite to form diazonium salts, which can be used to produce a series of
benzene derivatives and azo compounds.
Application:
Aniline is predominantly used as a chemical intermediate for dyes, drugs, explosives, plastics, and photographic and rubber chemicals. Many chemicals can be made from Aniline, including:
Isocyanaates for the urethane industry
Antioxidants, activators, accelerators, and other chemicals for the rubber industry
Indigo, acetoacetanilide, and other dyes and pigments for a variety of applications
Diphenylamine for the rubber, petroleum, plastics, agricultural, explosives, and chemical industries
Various fungacides and herbicides for the agricultural industry
Pharmaceutical, organic chemical, and other products
