Triethanolamine TEA
Triethanolamine is a colorless to pale yellow, hygroscopic viscous liquid with slight ammoniacal odor. We are supplier and exporter of TEA.


If RXH is not acid enough to release a proton at alkaline pH, as it is the case with amines, then the reaction has to be carried out in two steps. During the first step the first EO mole is added at acid pH, so that the amine is transformed in ammonium. The reaction produce the mono-, di- and tri-ethanol amines. 

Proton release from ammonium NH4+ → NH3 + H+ (here RX- is NH3) Then, the three condensation reactions: 


NH3 + EO → NH2CH2CH2OH (mono-ethanol amine MEA)
NH2CH2CH2OH + EO → NH(CH2CH2OH)2 (di-ethanol amine DEA)
NH-(CH2CH2OH)2 + EO → N(CH2CH2OH)3 (tri-ethanol amine TEA) 

With an alkyl amine, first the alkyl ammoniumion is formed and it is deprotonated: 

RNH3+ → RNH2 + H+ (here RX- is RNH2)
RNH2 + EO → RNH-CH2CH2OH (mono-ethanol alkyl amine)
RNH-CH2CH2OH + EO → RN(CH2CH2OH)2 (di-ethanol alkyl amine) 

Once the ethanol amine is attained, the EO polycondensation is carried out at alkaline pH as previously. In many instance the first ethoxylation is stopped when the monoethanol alkyl amine is formed in order to avoid the polycondensation in more than one chain.

Use industrial and consumer based:

Triethylamine is an important commercial chemical. It is used as a curing catalyst in foundry molds (foundry is a factory in which metals are cast into different shape by keeping in a container or mold after removing which the metal solidifies and gains that shape), and in particle-board adhesives. It is used for the precipitation and purification of antibiotics. It is used for the production of polycarbonate resins. Triethylamine is found in tobacco smoke, two household use products (floor finish, stump and vine killer) and is approved for use in food and food packaging.


TRIETHYLAMINE is a clear colorless liquid with a strong ammonia to fish-like odor.Vapors irritate the eyes and mucous membranes. Produces toxic oxides of nitrogen when burned.

TES mixes easily with water.
