Methyl Diethanolamine
Methyldiethanolamine, also known as ''N''-methyl diethanolamine and more commonly as MDEA, is the organic compound with the formula CH3N(C2H4OH)2. It is a colorless liquid with an ammonia odor. It is miscible with water, ethanol and benzene. A tertiary amine, it is widely used as a sweetening agent in chemical, oil refinery, syngas production and natural gas.Matthias Frauenkron, Johann-Peter Melder, Günther Ruider, Roland Rossbacher, Hartmut Höke "Ethanolamines and Propanolamines" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. Similar compounds are monoethanolamine (MEA), a primary amine, and diethanolamine (DEA), a secondary amine, both of which are also used for amine gas treating. MDEA's defining characteristic when compared to these other amines is its ability to preferentially remove H2S (and strip CO2) from sour gas streams. MDEA's popularity as a solvent for gas treating stems from several advantages it has when compared to other alkanolamines ...
