Methyldiethanolamine, also known as N-methyl diethanolamine and more commonly as MDEA, is the organic compound with the formula CH 3 N(C 2 H 4 OH) 2. It is a colorless liquid with an ammonia odor. It is miscible with water, ethanol and benzene .
DEA is used as a surfactant and a corrosion inhibitor.It is used to remove hydrogen sulfide and carbon dioxide from natural gas.. Diethanolamine is widely used in the preparation of diethanolamides and diethanolamine salts of long-chain fatty acids that are formulated into soaps and surfactants used in liquid laundry and dishwashing detergents, cosmetics, shampoos and hair conditioners.

MDEA may refer to: . Methyl diethanolamine (N-methyl-diethanolamine), CH 3 N(C 2 H 4 OH) 2, a chemical used for amine gas treating, also known as gas sweetening or acid gas removal, the removal of hydrogen sulfide and carbon dioxide from gasses in the petrochemical industry
N-Methylethanolamine is produced industrially by reacting ethylene oxide with excess methylamine in aqueous solution. This reaction yields a mixture of the 1:1 addition product NMEA (1) and - by a further addition of another ethylene oxide - the 1:2 addition product methyl diethanolamine (MDEA) (2):
The alumina-catalyzed reaction makes diethylamine from ethanol and ammonia.Diethylamine is obtained together with ethylamine and triethylamine.Annual production of the three ethylamines was estimated in 2000 to be 80,000,000 kg.
