Diethylaniline: An Organic Compound Used In Dyes and In the Production of Organic Chemicals

Diethylaniline


 Diethylaniline, also known as benzenamine, N,N-diethyl-, or N,N-Diethylanilin, is the organic compound that appears as a colorless to yellow liquid with a fishlike odor. It can be condensed with half an equivalent of benzaldehyde to produce brilliant green, an analogue of the very useful malachite green. It is strongly corrosive and can lead to skin irritation when inhaled, absorbed, or ingested.

Diethylaniline is used in dyes and in the production of organic chemicals. It has a molecular weight of 149.23 g/mol and an exact mass of 149.120449 g/mol. The chemical is colorless-to-yellow liquid with characteristic odor. It has a boiling point of 419.9 °F at 760 mm Hg and 198° F at 10 mm Hg and a melting point of -37.8 °F. As per the National Toxicology Program, Institute of Environmental Health Sciences, U.S., the flash point of the chemical is 185 °F.

The solubility  of diethylaniline is less than 1 mg/mL at 76.1° F. 1 g of the chemical dissolves in 70 ml of water at 12 °C. It is slightly sol in alcohol, chloroform, and ether. It is soluble in water 139 mg/l at 25 °C. As per Chemical Hazard Response Information System, U.S., the density of the chemical is 0.906.

abcr GmbH (Germany), Sigma-Aldrich (Germany), Acadechem Company Ltd. (Hong Kong), and MuseChem (US) are some of the major vendors of diethylaniline. The chemical is widely used in synthesis of pharmaceuticals. Production of the chemical and its use in the synthesis of dyes may result in its release to the environment through various waste streams. It can be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. Occupational exposure to the chemical may occur through inhalation and dermal contact with this compound at workplaces where it is produced or used.
