Aniline

IUPAC Name: Phenylamine

Source: An important chemical used in the production of dyes, pesticides, rubber, pharmaceuticals, and is also used as a solvent. It is used heavily as an intermediate in organic synthesis.

Summary: Aniline is an aromatic amine- an amine group attached to a benzene ring. It is a very important chemical used as an intermediate in organic synthesis. It is also used in the production of rubber, dyes, polyurethane foams, pharmaceuticals, and pesticides. It may also be used as a solvent in gasoline. It is soluble in water up to 36,000 mg/L at 25 C and has a density of 1.0217 g/mL at 20 C. The compound has an acid dissociation constant of pKa = 4.6. Aniline is classified by the EPA as a Hazardous Air Pollutant (HAPs). Koc values ranging from 43.8 – 497.7 indicate moderate to high mobility if found as a contaminant in soil. Mobility may be attenuated by the high reactivity of the amino group. Volatilization and biodegradation are expected to be major fate processes in water and soil. Photolysis may also be important in surface waters and exposed soil.
