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 .
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 ...
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
Methyldiethanolamine (MDEA) Diisopropanolamine (DIPA) Aminoethoxyethanol (Diglycolamine) (DGA) The most commonly used amines in industrial plants are the alkanolamines DEA, MEA, and MDEA. These amines are also used in many oil refineries to remove sour gases from liquid hydrocarbons such as liquified petroleum gas (LPG).
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):
Methylenedioxyphenethylamine (MDPEA). The substituted methylenedioxyphenethylamines (abbreviated as MDxx) represent a diverse chemical class of compounds derived from phenethylamines.
MDEA – methyl diethanolamine (aMDEA) MDL – methane drainage licence (United Kingdom), a type of onshore licence allowing natural gas to be collected "in the course of operations for making and keeping safe mines whether or not disused" MDSS – measured depth referenced to mean sea level zero datum – "subsea" level
