- Ethanolamine, also called 2-aminoethanol or monoethanolamine (often abbreviated as ETA or MEA), is an organic chemical compound with the formula HOCH2CH2NH2.
The molecule is both a primary amine and a primary alcohol (due to a hydroxyl group).
Ethanolamine is a colorless, viscous liquid with an odor reminiscent to that of ammonia.
Its derivatives are widespread in nature, e.g. lipids.
- Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound with the formula HN(CH2CH2OH)2.
Pure diethanolamine is a white solid at room temperature, but its tendency to absorb water and to supercool mean it is often encountered as a colorless, viscous liquid.
Diethanolamine is polyfunctional, being a secondary amine and a diol.
Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the alcohol groups, DEA is soluble in water.
Amides prepared from DEA are often also hydrophilic.
