Properties:
Physical properties: Monoethanolamine is a colorless viscous liquid with an ammonia smell. Its relative density is 1.0180, melting point is 10.5℃, and boiling point is 170℃. It is easily soluble in water, methanol, ethanol and acetone, and slightly soluble in ether and carbon tetrachloride.
Chemical properties: Monoethanolamine is strongly alkaline and can form salts with inorganic and organic acids, and react with acid anhydrides to form esters. The hydrogen atoms in its amino group can be replaced by acyl halides, alkyl halides, etc.
Stability: Monoethanolamine is stable at room temperature, but it may release absorbed gases when heated.
Applications:
Used as a solvent in chemical reactions: Monoethanolamine can be used as a solvent in organic synthesis to help dissolve, react and separate compounds.
Used as a surfactant: Monoethanolamine can be used as a surfactant to make detergents, emulsifiers, lubricants, etc.
Used in industrial processes such as decarbonization and desulfurization: Monoethanolamine can be used in decarbonization, desulfurization and other reactions in industrial processes such as petrochemicals, natural gas processing, and oil refining.
Used in the manufacture of bactericides and detergents: Monoethanolamine can be used as a raw material liquid for the manufacture of bactericides and detergents, and has good bactericidal and cleaning effects.
Other applications: Monoethanolamine is also used as a raw material for metal cleaning agents and rust inhibitors; a processing aid for the food industry; used in the manufacture of non-ionic detergents, emulsifiers, and automotive antifreeze; used as a raw material for the production of ethyleneamine series products; synthetic dyes (such as polycondensed turquoise blue 13G); used as a fluorescent brightener, mothproofing agent, and detergent; used as a neutralizer, plasticizer, vulcanizer, and foaming agent, etc.
