Diethylenetriamine (abbreviated DETA and also known as 2,2’-Iminodi(ethylamine)[2]) is an hydrocarbons. Diethylenetriamine is structural analogue of diethylene glycol. Its chemical properties resemble those for ethylene diamine, and it has similar uses. It is a weak base and its aqueous solution is alkaline. DETA is a byproduct of the production of ethylenediamine from ethylene dichloride.[3]

Reactions and uses

Diethylenetriamine is a common curing agent for Epoxy-resins in epoxy adhesives. In coordination chemistry, it serves as a tridentate ligand forming complexes such as Co(dien)(NO2)3.[4]

Like some related amines, it is used in oil industry for the extraction of acid gas.

Like ethylenediamine, DETA can also be used to sensitize nitromethane, making a liquid explosive compound similar to PLX. This compound is cap sensitive with an explosive velocity of around 6200 m/s and is discussed in patent #3,713,915. Mixed with unsymmetrical dimethylhydrazine it was used as Hydyne, a propellent for liquid-fuel rockets.

DETA has been evaluated for use in the Countermine System under development by the U.S. Office of Naval Research, where it would be used to ignite and consume the explosive fill of land mines in beach and surf zones.[5]
