Mono Ethanol Amine (MEA)
Monoethanolamine (MEA) is a clear, colorless, hygroscopic liquid produced by Shazand Petrochemical Company (Iran). Known for its dual functionality as both an amine and an alcohol, MEA serves as a versatile intermediate in numerous industrial and chemical processes.
With strong alkaline and solvent properties, Monoethanolamine is primarily used for gas treatment—specifically for the absorption of carbon dioxide (CO₂) and hydrogen sulfide (H₂S) in natural gas and refinery operations. Additionally, it is a key component in the manufacture of detergents, emulsifiers, pharmaceuticals, cosmetic formulations, and cement grinding aids.
MEA is also valued for its reactivity and compatibility with organic and inorganic acids, making it essential in surfactant synthesis, corrosion inhibitors, and textile finishing agents.

Monoethanolamine (MEA; CAS No. 141-43-5) is a simple ethanolamine compound containing one primary amine group and one hydroxyl (alcohol) group. It is a colorless, viscous liquid with a mild ammonia-like odor, characterized by its strong alkaline properties and high chemical reactivity.
Due to its dual functionality, MEA acts as both a weak base and a reactive alcohol, making it a valuable intermediate in various industrial and chemical processes. It is most commonly used in the sweetening of natural gas and coal gas, where it effectively removes acidic gases such as carbon dioxide (CO₂) and hydrogen sulfide (H₂S).
In addition to gas treatment, Monoethanolamine plays a vital role in the production of surfactants, ethanolamides, and detergent formulations. It is also used in the manufacture of ethyleneamines, corrosion inhibitors, and textile treatment chemicals due to its excellent reactivity and solubility in both water and organic solvents.

Viscous Liquid:
MEA is a moderately viscous liquid at room temperature, allowing for easy handling and blending in both continuous and batch chemical processes. Its viscosity ensures stable flow control and consistent reactivity in gas treatment and formulation systems.
Colorless Appearance:
The compound is colorless and transparent, indicating high purity and suitability for industrial and chemical-grade applications. Its clarity ensures compatibility with high-specification formulations such as detergents, surfactants, and gas scrubbing solutions.
Completely Miscible with Water:
Monoethanolamine is fully miscible in water in all proportions, forming stable aqueous solutions ideal for acid gas absorption and aqueous chemical reactions. This complete solubility enhances its performance in amine-based gas treatment systems.
Soluble in Ethanol and Acetone:
Beyond water, MEA is also readily soluble in ethanol, acetone, and other polar organic solvents, offering formulation flexibility in a wide range of industrial, cleaning, and surface-active agent applications.
