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. Production and usesDiethylamine is manufactured 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.[5] 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. Diethylamine is also sometimes used in the illicit production of LSD. Supramolecular structureDiethylamine is the smallest and simplest molecule that features a supramolecular helix as its lowest energy aggregate. Other similarly sized hydrogen-bonding molecules favor cyclic structures.[6] SafetyDiethylamine has low toxicity, but the vapor causes transient impairment of vision.[5] References1. ^Merck Index, 12th Edition, 3160 2. ^{{cite book | title = Nomenclature of Organic Chemistry : IUPAC Recommendations and Preferred Names 2013 (Blue Book) | publisher = The Royal Society of Chemistry | date = 2014 | location = Cambridge | page = 671 | doi = 10.1039/9781849733069-FP001 | isbn = 978-0-85404-182-4}} 3. ^1 2 {{PGCH|0209}} 4. ^1 {{IDLH|109897|Diethylamine}} 5. ^1 Karsten Eller, Erhard Henkes, Roland Rossbacher, Hartmut Höke "Amines, Aliphatic" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2005. {{DOI|10.1002/14356007.a02_001}} 6. ^{{cite journal |author1=Felix Hanke |author2=Chloe J.
