Sign in to saveAlso known as aminoethane, 1-aminoethane, monoethylamine, ethyl amine, ethanamine
Ethylamine, also known as ethanamine, is an organic compound with the formula CH3CH2NH2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines. Ethylamine is widely used in chemical industry and organic synthesis. It is a DEA list I chemical by 21 CFR § 1310.02.

Ethylamine, also known as ethanamine, is an organic compound with the formula CH3CH2NH2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines. Ethylamine is widely used in chemical industry and organic synthesis. It is a DEA list I chemical by 21 CFR § 1310.02.
==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. It is also produced by reductive amination of acetaldehyde. CH3CHO + NH3 + H2 → CH3CH2NH2 + H2O
