Monoethanolamine (MEA)
MONOETHANOLAMINE (MEA) INTRODUCTION
Monoethanolamine (MEA), also referred to as ethanolamine or 2-aminoethanol, is a clear and thick liquid with a subtle odor. This organic compound incorporates both amine and alcohol functional groups. MEA serves as a crucial raw material in the manufacturing of detergents, emulsifiers, and pharmaceuticals. Furthermore, MEA finds application as a corrosion inhibitor and acts as a gas-scrubbing agent to eliminate carbon dioxide and hydrogen sulfide from natural gas and refinery streams. Its versatility extends to functioning as a solvent for various substances, including resins, dyes, and waxes. In industrial processes, MEA plays a role in the production of specific herbicides like glyphosate and contributes to the synthesis of amino acids such as alanine and glycine. Despite its utility, MEA should be handled with care as it can pose health risks if ingested or inhaled, leading to skin and eye irritation. Hence, appropriate precautions are necessary when working with this substance.
- MEA has an unpleasant ammonia-like odor
- Monoethanolamine chemical formula is C2H7O2
Monoethanolamine is a very useful product in the industry, we will get to know the most important uses and applications of the MEA in the next section. Monoethanolamine is an organic compound known as aminoethanol, beta-aminoethyl alcohol, ethylamine. Monoethanolamine is produced by the reaction of ethylene oxide with liquid ammonia. It is a colorless substance with an unpleasant and unpleasant smell, similar to the smell of fish and ammonia.
STRUCTURE OF MONOETHANOLAMINE
This molecule consists of first-type amine and first-type alcohol and is a colorless and viscous liquid with a smell similar to ammonia. This material is used in detergent, agriculture, gas purification, metal working fluids, ink preparation, dyeing and textile industries.
PRODUCTION OF MONOETHANOLAMNE
Monoethanolamine (MEA) is produced by the reaction between ethylene oxide and aqueous ammonia. The reaction rate can be controlled by changing the stoichiometry of the reactants. It should be noted that this reaction is exothermic and its control is necessary to prevent unwanted events.
PROPERTIES OF MONOETHANOLAMNE
It is mainly used in moistening natural gas and coal gas and as a soap or amide in heavy detergents. This ethanol is used in the production of ethylene amines. The primary applications of this base are for the production of emulsifiers, polishing, pharmaceuticals, corrosion inhibitors and chemical intermediates.
APPLICATION OF MONOETHANOLAMNE
APPLICATION IN DETERGENTS: Formulation of detergents and dishwashers, multi-purpose detergents and disinfectants are recommended. This material can also be used as a neutralizing agent in the formulation of car wash shampoos, anti-grease agents, wax removers.
IN AGRICULTURE: Used as a neutralizing agent for anionic emulsifiers.
IN GAS PURIFICATION: Ethanolamines can be used to purify natural gas and residual petroleum gas in carbon dioxide absorption. In gas systems containing carbon dioxide, this material plays an important role in the production of ammonia, liquid carbon dioxide and dry ice.
OTHER USES: Due to its reaction with fatty acids or coconut oil, it is recommended as a synthesis intermediate for the production of the corresponding alkanol amides. This product can be used in various industrial sectors such as detergents, lubricating oils, health products.
This substance can also be used in the formulation of pharmaceutical products. It is used for adhesives, gums, latex, corrosion inhibitors, pH controllers, synthesis intermediates. They are also effective in varnishes, paints, waxes and wetting agents, polishes, polymerization agents and catalysts for polyurethane resins.
