'''Triethanolamine''' or '''trolamine''' (abbreviated as '''TEOA''' or '''TELA''', but rarer '''TEA''', which is more often used for [[triethylamine]]) is a viscous organic compound that is both a tertiary amine and an alcohol (a triol to be exact). It has the formula '''(OHCH<sub>2</sub>CH<sub>2</sub>)<sub>3</sub>N'''.<br />
<br />
==Properties==<br />
===Chemical===<br />
Triethanolamine is a strong base and readily reacts with acids. In the presence of water, it will readily absorb carbon dioxide from air to form its corresponding carbonate and bicarbonate salts.<br />
<br />
===Physical===<br />
Triethanolamine is a colorless odorless viscous liquid, miscible with many organic solvents. Degraded samples appear yellowish.<br />
<br />
==Availability==<br />
Triethanolamine is sold by chemical suppliers.<br />
<br />
Triethanolamine is found in many OTC products, like sunscreen lotions, liquid laundry detergents, dishwashing liquids, general cleaners, hand sanitizers, polishes, etc. However, there is too little TEA in these products to be a viable source.<br />
<br />
TEOA is listed under Schedule 3, part B of the Chemical Weapons Convention as it can be used in the manufacture of HN3 nitrogen mustard. Suspicious transactions may be monitored.<br />
<br />
==Preparation==<br />
Triethanolamine is produced by reacting [[ethylene oxide]] with aqueous [[ammonia]]. The reaction also produces [[ethanolamine]] and [[diethanolamine]]. The ratio of the products can be controlled by changing the stoichiometry of the reactants. <br />
<br />
==Projects==<br />
*Carbon dioxide scrubber<br />
*Synthesis of trolnitrate<br />
*Complexing agent in amateur photography and electroless plating<br />
<br />
==Handling==<br />
===Safety===<br />
Triethanolamine is irritant and may cause allergies.<br />
<br />
===Storage===<br />
Triethanolamine should be kept in closed plastic or glass bottles.<br />
<br />
===Disposal===<br />
Should be mixed with a more flammable solvent and incinerated.<br />
<br />
