Mono Ethanolamine (CAS 141-43-5) is an organic amine that combines amine and alcohol functional groups in one molecule, appearing as a colorless, viscous liquid with a mild ammonia-like odor, and it serves gas treatment, cement grinding aids and textile finishing as a reactive alkaline intermediate. It is an organic compound containing both amine and alcohol functional groups, offering strong alkalinity and reactivity.

Mono Ethanolamine
Applications
Widely used in gas treatment for removing acidic gases such as CO₂ and H₂S in refinery and natural gas operations. It is also employed in detergents, emulsifiers, corrosion inhibitors, and surfactant intermediates. In cement grinding aids and textile finishing, MEA provides stabilization and dispersion control.
Safety & Risks
Corrosive and irritant; may cause burns to skin and eyes. Avoid contact with strong oxidizers and acids.
Packaging
Supplied in 200 kg HDPE drums or 1,000 L IBC tanks. Store in a cool, dry, and well-ventilated area.
