Diethanolamine, often abbreviated as dea, is an organic compound with the formula hn(ch2ch2oh)2. This colourless liquid is polyfunctional, being a secondary amine and a dialcohol. Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the alcohol groups, dea is soluble in water, even hygroscopic. Amides prepared from dea are often also hydrophilic. Properties: 1. Molecular formula c4h6hn(oh)2 2. Molar mass 105. 14 g/mol 3. Density 1. 090 g/cm3 4. Melting point 28. 0 °c 5. Boiling point - 217 °c 6. Solubility in water soluble vapor pressure < 0. 01 hpa (20 °c).
