What is Monoethanolamine (MEA)?
Monoethanolamine, also known as MEA or ethanolamine, is a clear liquid made by reacting ethylene oxide with ammonia. This process produces a chemical with the formula C₂H₇NO, molecular weight 61.083, and density 1.02 g/cm³; it is a colorless transparent viscous liquid. When cooled, it turns into a white crystalline solid. It has a slight ammonia-like odor, strong alkalinity, and hygroscopic properties. It is easily soluble in water and alcohols, slightly soluble in benzene and ether. Its chemical properties are highly active, allowing it to react with various acids to form esters, amides, and salts. Since it contains both an alcohol group (-OH) and an amine group (-NH₂), monoethanolamine behaves as a powerful base and a mild alcohol.
Important Features:
- Monoethanolamine formula: C₂H₇NO
- Monoethanolamine pH: Around 11–12 in water
- Molecular weight: 61.08 g/mol
- CAS number: 141-43-5
- Appearance: Clear liquid
- Solubility: Fully soluble in water and most solvents
- Boiling point: About 170°C
- Odor: Mild, ammonia-like
Because of these properties, Monoethanolamine (cas number 141-43-5) has multiple uses and is widely applied in chemical industry, cosmetics, detergents, coatings, and agrochemicals.Furthermore, it is safe to store and handle when following basic safety instructions.
