Methyl Monoethanolamine (MMEA) is an alkanolamine with the formula CH3NHCH2CH2OH.
Methyl Monoethanolamine (MMEA) is flammable, corrosive, colorless, viscous liquid.
Methyl Monoethanolamine (MMEA) is an intermediate in the biosynthesis of choline.
With both an amine and a hydroxyl functional groups, it is a useful intermediate in the chemical synthesis of various products including polymers and pharmaceuticals.
Methyl Monoethanolamine (MMEA) is also used as a solvent, for example in the processing of natural gas, where it is used together with its analogs ethanolamine and dimethylethanolamine.
Production
Methyl Monoethanolamine (MMEA) is produced industrially by reacting ethylene oxide with excess methylamine in aqueous solution.
This reaction yields a mixture of the 11 addition product NMEA, and - by a further addition of another ethylene oxide - the 12 addition product methyl diethanolamine (MDEA).
In order to obtain high yields of the desired target product, the reactants are continuously fed to a flow reactor and reacted with a more than two-fold excess of methylamine.
In the downstream process steps, the excess methylamine and the water is removed and NMEA (bp. 160 °C) and MDEA (bp. 243 °C) are isolated from the product mixture by fractional distillation.
The poly(methyl-ethanolamine) formed by further addition of ethylene oxide to methylethanolamine remains in the distillation bottoms.
Properties
Methyl Monoethanolamine (MMEA) is a clear, colorless, hygroscopic, amine-like smelling liquid which is miscible with water and ethanol in any ratio.
Aqueous solutions react strongly basic and are therefore corrosive.
Methyl Monoethanolamine (MMEA) is easily biodegradable and has no potential of bioaccumulation due to its water miscibility.
NMEA is not mutagenic, but in the presence of nitrite, carcinogenic nitrosamines can be formed from the compound, as it is a secondary amine.
Uses:
Like other alkylalkanolamines, N-methylethanolamine is used in water- and solvent-based paints and coatings as a solubilizer for other components, such as pigments and as a stabilizer.
In cathodic dip-coating, Methyl Monoethanolamine (MMEA) serves as cation neutralizer for the partial neutralization of the epoxy resin.
Methyl Monoethanolamine (MMEA) also serves as a chain extender in the reaction of high molecular weight polyepoxides with polyols.
Being a base, Methyl Monoethanolamine (MMEA) forms neutral salts with fatty acids, which are used as surfactants (soaps) with good emulsifying properties and find applications in textile and personal care cleansing products.
When bleaching cotton-polyester blends, NMEA is used as a brightener.
By methylation of Methyl Monoethanolamine (MMEA), dimethylaminoethanol and choline [(2-hydroxyethyl)-trimethyl-ammonium chloride] can be prepared.
In the reaction of Methyl Monoethanolamine (MMEA) with fatty acids, long-chain N-methyl-N-(2-hydroxyethyl)amides are formed upon elimination of water.
These are used as neutral surfactants.
Such amides also act as flow improvers and pour point depressants in heavy oils and middle distillates.
By catalytic oxidation of Methyl Monoethanolamine (MMEA), the non-proteinogenic amino acid sarcosine is obtained.
Methyl Monoethanolamine (MMEA) plays a role as a building block for the synthesis of crop protection compounds and pharmaceuticals, such as in the first stage of the reaction sequence to the antihistamine and antidepressant mianserin (Tolvin) and to the non-analgesic Nefopam (Ajan).
In analogy to other aziridines, N-methylaziridine can be obtained by a Wenker synthesis from Methyl Monoethanolamine (MMEA).
