Ethylamine is a chemical compound with the formula CH3CH2NH2. It has a strong ammonia-like odor. It is miscible with virtually all solvents and is considered to be a weak base, as is typical for amines. Ethylamine is widely used in chemical industry and organic synthesis. It is also used in cigarettes.[citation needed]
Ethylamine, like some other amines, has the unusual property of dissolving lithium metal to give the ion [Li(amine)4]+ and the solvated electron. Evaporation of these solutions, gives back lithium metal. Such solutions used for the reduction of unsaturated organic compounds such as naphthalenes[2] and alkynes.
[edit] Synthesis and reactions
Ethylamine can be prepared in a laboratory by reaction of ethylene with ammonia in the presence of a catalyst.
- H2C=CH2 + NH3 → CH3CH2NH2
It can also be synthesized from acetaldehyde and ammonium chloride.[citation needed]
- 2 CH3CHO + NH4Cl → CH3CH2NH3Cl + CH3CO2H
- CH3CH2NH3Cl + NaOH → CH3CH2NH2 + NaCl + H2O
Reaction of ethylamine with sulfuryl chloride followed by oxidaton of the sulfonamide give diethyldiazene, EtN=NEt.[3]
It is a basic compound.
