Diethylenetriamine (DETA)

Diethylenetriamine is a common curing agent for epoxy resins in epoxy adhesives and other thermosets. It is N-alkylated upon reaction with epoxide groups forming crosslinks. In coordination chemistry, it serves as a tridentate ligand forming complexes such as Co(dien)(NO₂)₃. 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.
