Monoethanolamine (MEA CAS 141-43-5): Key Industrial Uses And Benefits

Monoethanolamine (MEA CAS 141-43-5), chemical formula C2H7NO, also known as monoethanolamine, is a colorless, transparent liquid with an ammonia odor and strong hygroscopic properties. Due to its unique chemical properties, monoethanolamine plays an indispensable role in many industries.

Monoethanolamine (MEA) Chemical Properties

Physical State: MEA is a colorless, transparent, viscous liquid at room temperature. It may solidify into a white crystalline solid at low temperatures and has a faint ammonia odor. Its density is 1.02 g/cm³, boiling point 170.5℃, melting point 10.5℃, and flash point 93.3℃ (open cup), indicating that its flammability requires high temperature or open flame to trigger.

• Solubility: Polar solvent: Completely soluble in water (infinite solubility at 20℃), forming an alkaline solution (5% solution pH≈11.7).
• Organic solvent compatibility: Easily soluble in ethanol and acetone, slightly soluble in benzene, diethyl ether, and carbon tetrachloride, and partially soluble in chloroform.
• Hygroscopicity: Absorbs moisture from the air; requires sealed storage to prevent deterioration.

Monoethanolamine (MEA CAS 141-43-5) Uses

Monoethanolamine (2-aminoethanol) has wide industrial applications. Its main uses are summarized below:
Chemical reagent and solvent:

• Monoethanolamine (2-aminoethanol) can be used as a reagent in chemical synthesis, participating in various chemical reactions.
• It can also be used as a solvent in some chemical reactions.

Dye and rubber industry:

• Monoethanolamine (MEA) can be used as an intermediate in dye synthesis.
• In rubber manufacturing, it can be used as an accelerator to improve the vulcanization rate and performance of rubber.

Corrosion inhibitor:

• Ethanolamine has the effect of inhibiting metal corrosion and can be used to protect metal surfaces.
• It acts as a corrosion inhibitor in boiler water treatment, automotive engine coolants, drilling and cutting oils, and other types of lubricating oils.

New Energy Sector:

In the production of biodiesel, adding ethanomine can act as a decolorizing agent, improving the purity of the biodiesel.

Surfactants:

• MEA (CAS 141-43-5) possesses excellent emulsifying properties and can be used to prepare various emulsifiers, such as those used in detergents and cosmetics.
• It is one of the main raw materials for surfactants. It can be used directly as a surfactant or synthesized with various acids to form important and commonly used surfactants, such as alkanolamides and triethanolamine dodecylbenzenesulfonate.

Plastics and Rubber Industry:

In the plastics industry, MEA (CAS 141-43-5) can be used as a plasticizer to improve the softness and processing properties of products.

In the rubber and ink industries, it can also be used as a neutralizing agent, vulcanizing agent, accelerator, and foaming agent.

Gas Absorption:

• MEA is commonly used as an absorbent for acidic gases such as carbon dioxide. It features fast absorption rate and low cost, and is widely used in the carbon dioxide absorption process in the power industry.
• It is also used for the absorption of acidic gases (such as hydrogen sulfide) in petroleum gas, natural gas, and other gases.

Textile Industry:

• In the textile industry, MEA (monoethanolamine) can be used as a whitening agent in dyeing and printing to improve the whiteness and luster of fabrics.
• It can also be used to prepare moth repellents to protect fabrics from insect damage.

In addition, monoethanolamine can also be used as a fluorescent whitening agent, antistatic agent, and detergent.
