Monoethanolamine (MEA)
CAS 141-43-5C2H7NO61.08 g/mol
Monoethanolamine (MEA) is a critical component in gas treatment, particularly for the removal of acidic gases like CO2 and H2S from natural gas and refinery operations. Key to the petroleum and gas industry, MEA's effectiveness in acid gas capture makes it indispensable for efficient plant operations. It appears as a colorless, clear viscous liquid and is available in high purity grades. Major uses include surfactant synthesis, textile processing, and as a pH adjuster in various formulations. Monoethanolamine finds use across sectors like oil and gas, cleaning, textiles, and agrochemicals.
Main applicationGas treatment — Absorbs CO2 and H2S in gas processing

Monoethanolamine (C2H7NO) is supplied as a colorless, clear, and viscous liquid with a mild ammonia-like odor. It is commercially available in various purity grades, including a typical purity of 99.5%. MEA functions well in amine scrubbing processes due to its ability to absorb CO2 and H2S, making it essential in gas purification units. High purity grades ensure minimal water content, crucial for efficient use in industrial formulations. When ordering, specify the concentration and grade to match operational needs. It is typically offered in bulk, including 210 kg drums, supporting large-scale industrial usage.

The CAS registry number for Monoethanolamine (MEA) is 141-43-5. Its chemical formula is C2H7NO, with a molecular weight of 61.08 g/mol. Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.
What are the other names for Monoethanolamine (MEA)?
Monoethanolamine (MEA) is also referred to as Ethanolamine, MEA and 2-Aminoethanol. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.
What grade of Monoethanolamine (MEA) is supplied?
Monoethanolamine (MEA) is supplied as Industrial grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.
What concentration is Monoethanolamine (MEA) supplied at?
Monoethanolamine (MEA) is supplied at a concentration of 15-30% wt%. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.
What is the purity of Monoethanolamine (MEA)?
The purity/assay figure recorded for Monoethanolamine (MEA) is 99.5%. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.
What does Monoethanolamine (MEA) look like?
Monoethanolamine (MEA) is described as colorless, clear, viscous liquid. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.
What is Monoethanolamine (MEA) used for?
Common applications include gas treatment — Absorbs CO2 and H2S in gas processing, surfactant synthesis — Reacts with fatty acids to form emulsifiers, textile & fiber processing — Used as pH adjuster and dye leveling agent, industrial cleaning — Employed in degreasing and scale removal, cement grinding aid — Reduces agglomeration, improving mill throughput and agrochemical formulations — Neutralizes and stabilizes pesticides. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.
Which industries use Monoethanolamine (MEA)?
