Diethylenetriamine - Wikipedia

Diethylenetriamine (abbreviated Dien or DETA) and also known as 2,2’-Iminodi(ethylamine)) is an organic compound with the formula HN(CH2CH2NH2)2. This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple 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. 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. 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.

Tris(2-aminoethyl)amine
Tris(2-aminoethyl)amine is the organic compound with the formula N(CH2CH2NH2)3. This colourless liquid is soluble in water and is highly basic, consisting of a tertiary amine center and three pendant primary amine groups. Tris(2-aminoethyl)amine is commonly abbreviated as tren or TREN. It is used a crosslinking agent in the synthesis of polyimine networks and a tripodal ligand in coordination chemistry. Tren is a C3-symmetric, tetradentate chelating ligand that forms stable complexes with transition metals, especially those in the 2+ and 3+ oxidation states.

Ethylenediamine
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. This colorless liquid with an ammonia-like odor is a basic amine. It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. Ethylenediamine is the first member of the so-called polyethylene amines. Ethylenediamine is produced industrially by treating 1,2-dichloroethane with ammonia under pressure at 180 °C in an aqueous medium: In this reaction hydrogen chloride is generated, which forms a salt with the amine.
