Diethylamine

Diethylamine is an organic compound with the formula (CH₃CH₂)₂NH. It is a secondary amine. It is a flammable, weakly alkaline liquid that is miscible with most solvents. It is a colorless liquid, but commercial samples often appear brown due to impurities. It has a strong ammonia-like odor

Diethylamine is made by the alumina-catalyzed reaction of ethanol and ammonia. It is obtained together with ethylamine and triethylamine. Annual production of three ethylamines was estimated in 2000 to be 80,000,000 kg.

It is used in the production of corrosion inhibitor N,N-diethylaminoethanol, by reaction with ethylene oxide. It is also a precursor to a wide variety of other commercial products.
