N-methyldiethanolamine (MDEA), also known as methylaminodiethanol, N,N-bis(2-hydroxyethyl)methylamine
Molecular weight 119.2, boiling point 246~248°C, flash point 260°C, freezing point -21°C, boiling point 247°C
Properties: Colorless or light yellow viscous liquid, easily soluble in water and alcohol, slightly soluble in ether. combustible. Non-toxic, it is a new type of selective desulfurization and decarburization solvent with excellent performance. It has the advantages of high selectivity, less solvent consumption, remarkable energy saving effect, and not easy to degrade.
Purpose
This product is mainly used to remove hydrogen sulfide in natural gas, refinery gas, synthesis gas and coal gas, and decarburization of industrial gases such as synthetic ammonia. It can also be used as a monomer for synthesizing medicine and coatings.
Application field
Widely used in oil field gas and coal gas desulfurization purification emulsifier and acid gas absorbent, acid-base control agent, polyurethane foam catalyst. With the participation of activators, carbon dioxide in synthetic ammonia can be removed, so it has been gradually promoted in the absorption of carbon dioxide in flue gas in recent years. In addition, MDEA can also be used as insecticide, emulsifier, semi-finished product of fabric auxiliaries, intermediate of antineoplastic drug nitrogen mustard hydrochloride, catalyst of urethane coating, fiber auxiliaries, etc., and also a kind of paint Drying agent.
