Monoethanolamine (MEA)
Chemical Formula: C?H?NO
Molecular Weight: 61.08 g/mol
Monoethanolamine (MEA) is a clear, colorless to pale yellow liquid with an ammonia-like odor. It is a hygroscopic organic compound that combines the properties of both amines and alcohols, giving it excellent reactivity and versatility. MEA is completely miscible with water and alcohols and serves as an essential raw material in gas treatment, detergents, emulsifiers, and corrosion inhibitors.
