acetonitrile
Acetonitrile, colorless liquid, highly volatile, has excellent solvent performance and can be dissolved. Various organic, inorganic and gaseous substances. It is infinitely miscible with water and alcohol. Acetonitrile is an important organic intermediate, which can take place typical nitrile reactions and is used to prepare many typical nitrogen-containing compounds. Acetonitrile can be used as a solvent for synthesizing vitamin A and its intermediates, and as an active medium solvent for manufacturing vitamin B1 and amino acids. It can replace chlorinated solvent. be used for ethylene base coating It is also used as an extractant of fatty acids, an alcohol denaturant, and has many uses in fabric dyeing, lighting, spice manufacturing and light-sensitive material manufacturing.
Chemical property: colorless transparent liquid, miscible with water.
1. Acetonitrile is a stable compound, which is not easy to be oxidized or reduced, but between carbon and nitrogen is three key , easy to occur addition reaction, such as addition with hydrogen halide, addition with hydrogen sulfide, addition with alcohol and addition with acid or anhydride in the presence of inorganic acid.
2. Hydrolysis occurs in the presence of acid or alkali, and further hydrolysis into acid:
3. Reduction to produce ethylamine.
4. React with Grignard reagent, and the product is obtained by hydrolysis.
Function editing
Acetonitrile is mainly used as solvent. For example, as solvent, synthetic fiber solvent and some special coating solvent. Solvent used in petroleum industry to remove tar, phenol and other substances from petroleum hydrocarbon. In the oil industry, it is used as a solvent for extracting fatty acids from animal and vegetable oils. When polar solvent with high dielectric constant is needed, binary azeotropic mixture formed by acetonitrile and water is often used: containing 84% acetonitrile, boiling point 76 ℃. Acetonitrile is an intermediate of spices and a raw material for manufacturing. It is also used as a denaturant for alcohol. In addition, it can also be used for synthesis, and has many uses in textile dyeing and lighting industries.
