What is MEA(Monoethanolamine) solvent?
Monoethanolamine (MEA) is an important organic amine compound with the chemical formula HOCH₂CH₂NH₂, exhibiting properties of both alcohols and amines.
Monoethanolamine (MEA) Physical Properties
At room temperature, Monoethanolamine (MEA) is a colorless, transparent, viscous liquid that may crystallize into a white solid at low temperatures. It possesses a faint ammonia odor. Its density is 1.02 g/cm³, boiling point is 170.5°C, melting point is 10.5°C, and flash point is 93.3°C (open cup), indicating its flammability requires high temperatures or open flames to ignite.
Solubility
- Polar Solvents: Completely soluble in water (infinite solubility at 20°C), forming an alkaline solution (pH ≈ 11.7 for a 5% solution).
- Organic Solvent Compatibility: Easily soluble in ethanol and acetone; slightly soluble in benzene, diethyl ether, and carbon tetrachloride; partially soluble in chloroform.
- Hygroscopicity: Absorbs moisture from air; must be stored sealed to prevent degradation.
Monoethanolamine (MEA) Chemical Properties
- Reacts with acid anhydrides to form esters (e.g., reacts with acetic anhydride to produce monoethanolamine acetate).
- Reacts with carbon disulfide to form thioxantholine (rubber industry intermediate).
- Under nickel catalysis, reacts with ammonia gas to form ethylenediamine (common chelating agent).
- Basicity: Exhibits strong basicity, reacting with inorganic acids (e.g., sulfuric acid, hydrochloric acid) and organic acids to form salts or esters.
- Oxidation Sensitivity: MEA (Monoethanolamine CAS 141-43-5) solvent is readily oxidized by SO₂ and O₂ in flue gases, causing solution discoloration to yellow or precipitation formation.

Industrial Uses of Monoethanolamine (MEA)
- Monoethanolamine solvent is used in the manufacture of various specialty textiles, agricultural chemicals, waxes, mineral and vegetable oils, paraffin wax, polishing agents, cutting oils, petroleum demulsifiers, and as an emulsifier and dispersant in cement additives.
- MEA is also an intermediate in resins, plasticizers, and rubber additives. Furthermore, ethanolamine is used in the textile industry as a lubricant and as a humectant and softener for leather.
- Ethanolamine is also an alkalizing agent in pharmaceuticals, a surfactant, an absorbent for acidic gases, and an important component in organic synthesis.
Applications of Monoethanolamine (MEA) in the Personal Care Industry
Monoethanolamine (MEA) solvent is widely used in cosmetics and personal care products, such as eyeliner, mascara, eyeshadow, blush, foundation, and powder, as well as perfumes, hair care products, hair dyes, perm kits, shaving products, sunscreens, skin care, and skin cleansing products. Additionally, MEA is used in certain perming and hair dyeing agents.
