Triethylenetetramine, abbreviated TETA and trien, is an organic compound with the formula [CH2NHCH2CH2NH2]2. This oily liquid is colourless but, like many amines, assumes a yellowish color due to impurities resulting from air-oxidation. It is soluble in polar solvents and exhibits the reactivity typical for amines. The branched isomer N(CH2CH2NH2)3 and piperazine derivatives also comprise commercial samples of TETA. Triethylenetetramine is prepared by heating ethylenediamine or ethanolamine/ammonia mixtures over an oxide catalyst. This process gives a variety of amines, which are separated by distillation and sublimation. The reactivity and uses of TETA are similar to those for the related polyamines ethylenediamine and diethylenetriamine. It was primarily used as a crosslinker ("hardener") in epoxy curing. The hydrochloride salt of triethylenetetramine, referred to as trientine hydrochloride, is a chelating agent, and is used to bind up and remove copper in the body to treat Wilson's disease, particularly in those who are intolerant to penicillamine. Some recommend trientine as first-line treatment, but experience with penicillamine is more extensive.
