Ethanolamine is an organic chemical compound that is also known as 2-aminoethanol, monoethanolamine, ETA, or MEA. The molecule is bifunctional in the sense that it contains both a primary amine and a primary alcohol. Ethanolamine is a colourless, viscous liquid with an ammonia-like odour. ETA molecules are a component of cellular membrane formation and thus a molecular building block for life. It was previously thought that ETA molecules only existed on Earth and on certain asteroids, but evidence was discovered in 2021 that ETA molecules exist in interstellar space.
According To Coherent Market Insights " The global ethanolamines market size is estimated at US$ 2.99 billion (revenue) and 1840.96 kilo tons (volume) in 2016 and is expected to expand at a CAGR of 4.4% in terms of revenue and 3.6% in terms of volume during the period 2017 – 2025. "
Derivatives of
ethanolamine are abundant in nature; for example, lipids serve as a precursor for a variety of N-acylethanolamines (NAEs), which modulate several animal and plant physiological processes such as seed germination, plant–pathogen interactions, chloroplast development, and flowering, as well as a precursor for the endocannabinoid anandamide when combined with arachidonic acid.
Ethanolamine is frequently used to alkalinize water in power plant steam cycles, including nuclear power plants with pressurised water reactors. This alkalinization is done to keep metal components from corroding. Because of its volatility, ETA (or a similar organic amine, such as morpholine) is chosen because it does not accumulate in steam generators (boilers) and crevices, but rather distributes relatively uniformly throughout the entire steam cycle. ETA is a key ingredient in the so-called "all-volatile treatment" of water in this application (AVT).
MEA and other ethanolamines are common ingredients in cleaning products such as floor and tile cleaners and laundry detergents. Ethanolamines, which act as surfactants in these products, aid in the removal of dirt, grease, and stains. Because of its ability to break down oil and grease, DEA is a common ingredient in industrial cleaning products such as engine degreasers and industrial strength detergents.
