What is Triethanolamine CAS 102-71-6?

Triethanolamine is a tertiary amino alcohol with the formula C₆H₁₅NO₃ and molecular weight about 149.19. It is commonly supplied as a viscous, colorless to pale yellow liquid and is also known as Trolamine, TEA, TEOA, 2,2',2''-nitrilotriethanol and tris(2-hydroxyethyl)amine.

Are TEA, Trolamine and TEOA the same material?

In this listing they all identify the same substance, CAS 102-71-6. However, TEA can sometimes be confused with triethylamine, so a purchase order should state the CAS number, intended grade and whether the material is neat or an aqueous form such as 85%.

Which specifications should be confirmed for Triethanolamine?

Key items are purity or amine assay, diethanolamine and ethanolamine limits, water content, color, density and pH test conditions. Common high-purity grades are about 99% or higher with diethanolamine below roughly 0.3-0.5% and water below about 0.2%.

What are the main uses of Triethanolamine?

It is used as a pH adjuster or neutralizer, emulsifier and surfactant intermediate. Major applications include metalworking fluids, cement grinding aids, textiles, cosmetics and personal care, and pharmaceutical buffer or emulsifier systems.

What should be considered for bulk or cold-weather handling of TEA?

Triethanolamine can become very viscous or partially solidify near its melting point of about 20-22 deg C, so tank, IBC and transfer lines may need temperature control or gentle heating. Confirm concentration basis, packaging, previous cargo, seals and unloading connections before dispatch.
