Ethylamines
Ethylamine, also known as ethanamine, is an organic compound with the chemical formula, formula CH3CH2NH2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscibility, miscible with virtually all solvents. It is a nucleophilic base (chemistry), base, as is typical for amines. Ethylamine is widely used in chemical industry and organic synthesis. Synthesis Ethylamine is produced on a large scale by two processes. Most commonly ethanol and ammonia are combined in the presence of an oxide catalyst: :CH3CH2OH + NH3 → CH3CH2NH2 + H2O In this reaction, ethylamine is coproduced together with diethylamine and triethylamine. In aggregate, approximately 80M kilograms/year of these three amines are produced industrially.Karsten Eller, Erhard Henkes, Roland Rossbacher, Hartmut Höke, "Amines, Aliphatic" Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2005. It is also produced by reductive amination of ace ...

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. Production and uses 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. Diethylamine is also sometimes used in the illicit production of LSD. Supramolecular structure Diethylamine is the smallest and simplest molecule that features a supramolecular helix A helix () is a shape like a corkscrew or spiral staircase. It is a type ...
