Diethylenetriamine is a accepted abating abettor for Epoxy-resins in adhesive adhesives. In allocation chemistry, it serves as a tridentate ligand basic complexes such as Co(dien)(NO2)3.

Like some accompanying amines, it is acclimated in oil industry for the abstraction of acid gas.

Like ethylenediamine, DETA can aswell be acclimated to sensitize nitromethane, authoritative a aqueous atomic admixture agnate to PLX. This admixture is cap acute with an atomic acceleration of about 6200 m/s and is discussed in apparent #3,713,915. Mixed with asymmetric dimethylhydrazine it was acclimated as Hydyne, a propellent for liquid-fuel rockets.

DETA has been evaluated for use in the Countermine System beneath development by the U.S. Office of Naval Research, area it would be acclimated to burn and absorb the atomic ample of acreage mines in bank and cream zones.
