Monoethanolamine (Mea) chemical inhibits metal corrosion and can be used to protect metal surfaces.
It serves as a corrosion inhibitor in boiler water treatment, automotive engine coolants, drilling and cutting oils, and various other lubricants.
During biodiesel production, adding Monoethanolamine (Mea) serves as a decolorizing agent to enhance biodiesel purity.
Monoethanolamine (Mea) exhibits excellent emulsifying properties, making it suitable for preparing various emulsifiers used in detergents, cosmetics, and other products.
As a primary raw material for surfactants, it can be used directly or synthesized with various acids to produce important common surfactants like alkanolamides and triethanolamine dodecylbenzenesulfonate.
In the plastics industry, Monoethanolamine (Mea) serves as a plasticizer, enhancing product flexibility and processability.
In rubber and ink manufacturing, it functions as a neutralizer, vulcanizing agent, accelerator, and foaming agent.
Monoethanolamine (Mea) is commonly employed as an absorbent for acidic gases like carbon dioxide, widely used in power generation for CO₂ capture processes.
It is also utilized to absorb acidic gases (e.g., hydrogen sulfide) from petroleum gas, natural gas, and other gases.
