    Triethylenetetramine Usage And Synthesis
    Description Triethylenetetramine (TETA and trien) also known as trientine (INN) when used medically, is an organic compound with the formula [CH2NHCH2CH2NH2]2. The pure freebase is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air- oxidation. It is soluble in polar solvents. The branched isomer tris(2-aminoethyl)amine and piperazine derivatives may also be present in commercial samples of Triethylenetetramine. The hydrochloride salts are used medically as a treatment for copper toxicity.
    Chemical Properties Triethylenetetramine is a corrosive liquid.
    Uses Triethylenetetramine is used as an amine hardener in epoxy resin of the bisphenol A type.It is used in synthesis of detergents, softeners, and dyestuffs; manufacture of pharmaceuticals; vulcanization accelerator of rubber; thermo setting resin; epoxy curing agent; lubricating-oil additive; analytical reagent for Cu, Ni; chelating agent; treatment of Wilson's disease.
    Production Methods Triethylenetetramine(TETA) is manufactured by reacting ethylene dichloride and ammonia under controlled conditions.
    Definition ChEBI: 2,2,2-tetramine is a polyazaalkane that is decane in which the carbon atoms at positions 1, 4, 7 and 10 are replaced by nitrogens. It has a role as a copper chelator. It is a tetramine and a polyazaalkane.
    Brand name Syprine (Merck).
    General Description A yellowish liquid. Less dense than water. Combustible, though may be difficult to ignite. Corrosive to metals and tissue. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion. Used in detergents and in the synthesis of dyes, pharmaceuticals and other chemicals.
    Chemical Properties Triethylenetetramine (TETA) is hygroscopic, corrosive, and has a strong ammoniacal odor. With water a crystalline hydrate is formed. Like DETA, it is completely miscible with water and many polar organic solvents, but less so with lipids; with CCl4 a violent reaction occurs. Its four pKa values are 3.32, 6.67, 9.20, and 9.92. Technical-grade TETA is sometimes available as a distillation cut that also contains branched isomers and cyclic compounds.
    Reactivity Profile Triethylenetetramine is a strong base; reacts violently with strong oxidants; attacks aluminum, zinc, copper and its alloys. Handling Chemicals Safely 198. p. 934).
