Short Description::
TEA
Long Description::
Triethanolamine TEA
Triethanolamine is a colorless to pale yellow, hygroscopic viscous liquid with slight ammoniacal odor. We are supplier and exporter of TEA.
Application::
T.E.A is used as intermediate in the manufacture of surface active agents, textile specialties, antirust compounds, waxes, polishes, herbicides, petroleum demulsifies, cement additives and cutting oils.
It also finds extensive use in the manufacture of Synthetic resins, as a solvent for casein, shellac and dyes, for increasing the penetration of organic liquids into wood and paper in the production of lubricants for textile industry and in making emulsions with mineral and vegetable oils, paraffin and waxes.

Product remark::
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.
