Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. It is also abbreviated TEA, yet this abbreviation must be used carefully to avoid confusion with triethanolamine or tetraethylammonium , for which TEA is also a common abbreviation.
Triethanolamine is used primarily in making surfactants, such as for emulsifier.It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in wate
Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a trimethylated derivative of ammonia.TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7]
In organic chemistry, the Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol (−OH) is oxidized to an aldehyde (−CH=O) or ketone (>C=O) using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine.
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2.The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation.
Diethylamine is obtained together with ethylamine and triethylamine. Annual production of the three ethylamines was estimated in 2000 to be 80,000,000 kg. [5] Diethylamine is used in the production of corrosion inhibitor N,N-diethylaminoethanol, by reaction with ethylene oxide. It is also a precursor to a wide variety of other commercial products.

This method affords significant amounts of byproducts, including diethylamine and triethylamine. [6] CH 3 CH 2 Cl + NH 3 + KOH → CH 3 CH 2 NH 2 + KCl + H 2 O. Ethylamine is also produced naturally in the cosmos; it is a component of interstellar gases. [7]
