Sub-Family: Alkanolamines
Physical State: Liquid

Product: Methyldiethanolamine
Abbreviation: MDEA
Names: 2,2′-(Methylazanediyl)di(ethan-1-ol); Bis(2-hydroxyethyl)(methyl)amine
: Methyldiethanolamine (MDEA) is a colorless, water-soluble liquid tertiary alkanolamine with the formula CH₃N(C₂H₄OH)₂ and a mild ammonia odor. It is widely used in natural gas processing and refinery operations for selective removal of hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from gas streams, making it a key solvent in acid gas removal and gas sweetening applications. MDEA is also used as an intermediate in the production of surfactants, personal care products, coatings, and other industrial chemicals.
