Dimethylamine is an organic compound with the formula (CH 3) 2 NH. This secondary amine is a colorless, flammable gas with an ammonia -like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%.
4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH 3) 2 NC 5 H 4 N. This white solid is of interest because it is more basic than pyridine, owing to the resonance stabilisation from the NMe 2 substituent.
N,N-Diethylmethylamine (diethylmethylamine, DEMA) is a tertiary amine with the formula C 5 H 13 N. N,N-Diethylmethylamine is a clear, colorless to pale yellow liquid at room temperature, and is used in various industrial and scientific applications including water desalination as well as analytical and organic chemistry.
This compound is a diamine in which the two dimethylamino groups are attached on the same side (peri position) of a naphthalene ring. This molecule has several very interesting properties; one is its very high basicity; another is its spectroscopic properties.
NDMA forms from a variety of dimethylamine-containing compounds, e.g. hydrolysis of dimethylformamide. Dimethylamine is susceptible to oxidation to unsymmetrical dimethylhydrazine, which air-oxidizes to NDMA. [15] In the laboratory, NDMA can be synthesised by the reaction of nitrous acid with dimethylamine: HONO + (CH 3) 2 NH → (CH 3) 2 NNO ...
Methylamine has been produced industrially since the 1920s (originally by Commercial Solvents Corporation for dehairing of animal skins). [4] This was made possible by Kazimierz Smoleński [] and his wife Eugenia who discovered amination of alcohols, including methanol, on alumina or kaolin catalyst after WWI, filed two patent applications in 1919 [5] and published an article in 1921.
Trimethylamine N-oxide (TMAO) is an organic compound with the formula (CH 3) 3 NO. It is in the class of amine oxides.Although the anhydrous compound is known, trimethylamine N-oxide is usually encountered as the dihydrate.
DMA is prepared commercially by the reaction of dimethylamine with acetic anhydride or acetic acid. Dehydration of the salt of dimethylamine and acetic acid also furnishes this compound: [5] CH 3 CO 2 H·HN(CH 3) 2 → H 2 O + CH 3 CON(CH 3) 2. Dimethylacetamide can also be produced by the reaction of dimethylamine with methyl acetate. [6]
