Monoethanolamine
Monoethanolamine is the most commonly studied alkanolamine and shares some reaction pathways with other ethanolamines including: secondary (eg, DEA), tertiary (eg, MDEA), cyclic (eg, 3-methanolpiperazine, 3-PM), and sterically hindered (eg, AMP) alkanolamines.

Biogasification of Waste Monoethanolamine Generated in Post Combustion CO2 Capture
Deshai Botheju, ... Rune Bakke, in Proceedings of the 2nd Annual Gas Processing Symposium, 2010

4.1 Aerobic Batch Tests
Monoethanolamine containing reactors consume more oxygen than the control, demonstrating Monoethanolamine degradation (Fig 1). 500 mg/L Monoethanolamine initial concentration show less ultimate BOD and slower reaction compared to 125 mg/L Monoethanolamine (Fig. 1(a)), explained by Monoethanolamine induced inhibition. Such inhibition was avoided in the second test by using the culture from the first test after longer adaptation and pH adjusted to neutral (Fig. 1 (b)). Monoethanolamine toxicity and inhibition has also been noticed by others (Lai and Shieh, 1996).

Conventional amine scrubbing for CO2 capture
G.T. Rochelle, in Absorption-Based Post-combustion Capture of Carbon Dioxide, 2016

3.9.1 Monoethanolamine (MEA)
Monoethanolamine is an important candidate for CO2 capture by amine scrubbing. ASEA Brown Boveri (ABB) Lummus built several small units scrubbing coal-fired flue gas with 20 wt% Monoethanolamine using carbon steel with a corrosion inhibitor. Fluor has commercialized 30 wt% Monoethanolamine in a number of units based on gas combustion. Numerous publications report extensive bench-scale and pilot plant results with MEA.

Monoethanolamine is the least expensive of the important absorption liquids. It is produced in large quantities from the reaction of ammonia and ethylene oxide, a primary raw material for antifreeze polyester. It is a primary amine near the optimum Acid Dissociation Constant (pKa), so it has an average rate of CO2 absorption and above average normalized capacity with excellent viscosity. Its heat of CO2 absorption is high, so it performs well with thermal-swing regeneration.

Unfortunately, Monoethanolamine is prone to oxidative degradation and its Tmax for thermal degradation is 120°C. Oxidation inhibitors, nitrogen sparging to remove dissolved oxygen, or other methods will be required to manage oxidation.

MonoEthanolAmine

MonoEthanolAmine Chemical Structure Composition.

Production
Monoethanolamine is produced by reacting ethylene oxide with aqueous ammonia.

This reaction produce monoethanolamine as well as diethanolamine and triethanolamine.

The ratio of each product can be controlled by the ratio of the reactants.

Uses
Monoethanolamine (MEA) is mainly used in detergents, personal-care products, textile, gas treating, wood treating, metal-working fluids, and catalysts for PU foams.

Monoethanolamine , also known as aminoethanol or colamine, belongs to the class of organic compounds known as 1, 2-aminoalcohols. These are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C2 atom. Monoethanolamine  exists as a liquid, soluble (in water), and an extremely weak acidic (essentially neutral) compound (based on its pKa). Monoethanolamine  has been found in human brain, pancreas and epidermis tissues, and has also been detected in most biofluids, including feces, breast milk, saliva, and blood. Within the cell, Monoethanolamine  is primarily located in the cytoplasm and myelin sheath. Monoethanolamine  exists in all eukaryotes, ranging from yeast to humans. Monoethanolamine  participates in a number of enzymatic reactions. In particular, Monoethanolamine  can be converted into O-phosphoMonoethanolamine  through the action of the enzyme choline/Monoethanolamine  kinase. Furthermore, Monoethanolamine  can be converted into O-phosphoMonoethanolamine  through its interaction with the enzyme choline/Monoethanolamine  kinase. Furthermore, Monoethanolamine  can be converted into O-phosphoethanolamine through the action of the enzyme choline/Monoethanolamine  kinase. Finally, Monoethanolamine  can be converted into O-phosphoethanolamine; which is mediated by the enzyme choline/ethanolamine kinase. In humans, Monoethanolamine is involved in phosphatidylcholine biosynthesis PC(22:2(13Z, 16Z)/16:1(9Z)) pathway, phosphatidylcholine biosynthesis PC(13m5/11m3) pathway, phosphatidylcholine biosynthesis PC(22:0/14:1(9Z)) pathway, and phosphatidylMonoethanolamine biosynthesis pe(22:5(7Z, 10Z, 13Z, 16Z, 19Z)/22:4(7Z, 10Z, 13Z, 16Z)) pathway. Outside of the human body, Monoethanolamine can be found in a number of food items such as allspice, lemon grass, pitanga, and date. This makes Monoethanolamine a potential biomarker for the consumption of these food products. Monoethanolamine is a potentially toxic compound. Monoethanolamine has been found to be associated with the diseases known as ethanolaminuria; Monoethanolamine has also been linked to several inborn metabolic disorders including propionic acidemia and maple syrup urine disease.

Human Metabolome Database (HMDB)
Monoethanolamine is a first generation monoethanolamine with antihistaminic property. Monoethanolamine competes with free histamine for binding at the histamine (H)-1 receptor thereby acting as an inverse agonist that combines with and stabilizes the inactive form of the H1-receptor thereby shifting the equilibrium toward the inactive state. This leads to a reduction of the negative symptoms brought on by H1-receptor binding.

NCI Thesaurus (NCIt)
Monoethanolamine appears as a clear colorless liquid with an odor resembling that of ammonia. Flash point 185°F. May attack copper, brass, and rubber. Corrosive to tissue. Moderately toxic. Produces toxic oxides of nitrogen during combustion.
