Ethanolamine is an organic chemical compound that is both a primary amine and a primary alcohol. Like other amines, monoethanolamine acts as a weak base / alkali. Ethanolamine is a flammable, corrosive, colourless, odourless liquid with a mild odour of ammonia. MEA is obtained from the reaction between ammonia and ethylene oxide.
USES FOR MONOETHANOLAMINE
Monoethanolamine is a chemical intermediate in the manufacture of surface-active agents, emulsifiers, and plasticizing agents; a gas-scrubbing agent for the absorption and removal of H2S and CO2 from refinery and natural gas streams; carbon dioxide and ammonia manufacturing.
- MEA is used in aqueous solutions for scrubbing acidic gases.
- It is used as feedstock in the production of detergents, emulsifiers, polishes, corrosion inhibitors, chemical intermediates.
- It is used to neutralise fatty acids like stearic acid and oleic acid to produce soaps etc.
- Reacting ethanolamine with ammonia gives the commonly used ethylenediamine.
- In Cement production it is used to enhance strength, reduce drying time and protect against the affects of freezing and thawing.
- In metal working fluids it is used to neutralize acid components in lubricants, prevent corrosion and rusting, and for proprietary corrosion inhibitors and biocides.
- In printing inks to control the pH.
- monoethanolamine pulping of beech and spruce wood for production of dissolving pulp.
- In agrochemicals it is used as neutralizer agent for anionic emulsifiers.
