Molecular format:C6H7N
CAS No:62-53-3
Product molecular structure:
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 one of the most important intermediates in the dye industry. It can be used in the dye industry to manufacture acid ink blue G, acid medium BS, acid soft yellow, direct orange S, direct rosé, indigo blue, disperse yellow brown, cationic rosé FG and reactive brilliant red X-SB, etc.; in organic pigments, it is used to manufacture golden red, golden red g, big red powder, phenocyanine red, oil soluble black, etc. It can also be used as a raw material for pharmaceutical sulfa drugs, and as an intermediate in the production of spices, plastics, varnishes, films, etc. It can also be used as a stabilizer in explosives, an explosion-proof agent in gasoline and as a solvent; it can also be used to manufacture hydroquinone and 2-phenylindole.
Aniline is an important raw material for the production of pesticides.
