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. A tertiary amine, it is widely used as a sweetening agent in chemical, oil refinery, syngas ...
An alternative to the use of amines involves membrane technology. However, membrane separation is less attractive due to the relatively high capital and operating costs as well as other technical factors. [4] Many different amines are used in gas treating: Diethanolamine (DEA) Monoethanolamine (MEA) Methyldiethanolamine (MDEA ...
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
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.

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):
3,4-Methylenedioxy-N-ethylamphetamine (MDEA; also called MDE and colloquially, Eve) is an empathogenic psychoactive drug. MDEA is a substituted amphetamine and a substituted methylenedioxyphenethylamine. MDEA acts as a serotonin, norepinephrine, and dopamine releasing agent and reuptake inhibitor. [1] Possession of MDEA is illegal in most ...

The thermal degradation rates for methyl diethanolamine (MDEA) and piperazine (PZ) are negligible, and PZ, unlike other metals, protect MDEA from oxidative degradation. [11] This increased stability of the MDEA/PZ solvent blend over MDEA and other amine solvents provides for greater capacity for and requires less work to capture a given amount ...
