About Pyridine. Pyridine is an organic compound, in the heterocyclic aromatic class, structurally similar to benzene, but with a carbon-hydrogen ring set substituted by a nitrogen atom. It is a yellowish to colorless liquid, with nauseating odor, miscible with water and most organic solvents. Pyridine was first synthesized in 1876, starting from acetylene and hydrogen cyanide, but gained commercial importance in the twentieth century, with production growing rapidly after World War II. The compound can be classified as a specialty chemical, since its sales are relatively lower in volume compared to commodity chemicals, with production at around 30000 tons per year. The main uses of pyridine are in areas where bioactivity is important, such as pharmaceutical and agricultural industries.
Chemical Formula. C5H5N
Commercial Grades. medicinal grade (99.9% minimum purity); spectrophotometric grade (99% minimum purity); and technical grade (95% minimum purity).
Uses. Pyridine is used mainly in herbicides; insecticides; plastics, resins and rubber production; and shampoo manufacturing. It is also used as plant growth regulator; starting material in the synthesis of vitamins and drugs; solvent in organic chemistry; surfactant; curing agent; and textile dying agent.
- Formaldehyde + acetaldehyde cofeed with ammonia (gas-phase catalytic cyclisation process)
- Acrolein + ammonia (gas-phase catalytic cyclisation process)
- Coal tar (isolation and purification)
Derivatives. 2-aminopyridine and other aminopyridines; 2-chloropyridine and other chloropyridines; pyridine-1-oxide and others pyridine oxides; nitropyridines; picoline; and piperidine.
