About Triethylenetetramine 1

Triethylenetetramine, abbreviated TETA and trien and also called trientine (INN), is an organic compound with the formula[CH2NHCH2CH2NH2]2. This oily liquid is colorless but, like many amines, assumes 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 TETA.

he reactivity and uses of TETA are similar to those for the related polyamines ethylenediamine and diethylenetriamine. It is primarily used as a crosslinker ("hardener") in epoxy curing.

The hydrochloride salt of TETA, referred to as trientine hydrochloride, is a chelating agent that is used to bind 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.

Versatile Industrial Applications

Triethylenetetramine is valued for its adaptability across industries such as chemical manufacturing, textiles, paper processing, and oil field operations. Its primary functions include serving as an epoxy curing agent, chelating agent, and corrosion inhibitor, making it essential in improving the performance of coatings, adhesives, metal treatment solutions, and specialty chemicals.

Safe Handling and Storage Practices

Given its corrosive and harmful properties, Triethylenetetramine should be handled with proper personal protective equipment. It should be kept tightly sealed in a cool, well-ventilated location, away from incompatible substances like acids and oxidizers, in accordance with stringent chemical storage and transport guidelines. Following these measures ensures both user safety and product integrity.

Chemical and Physical Properties

Triethylenetetramine exhibits a boiling point of 277C, melting at 40C, and possesses a low vapor pressure at room temperature, supporting its controlled industrial use. It is a clear to pale yellow liquid with an ammoniacal odor, refractive index of 1.4976 at 20C, and density of 0.982 g/cm. These attributes ensure its reliable performance in demanding applications.
