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%.
N-Methylmethanimine or N‐methyl methylenimine is a reactive molecular substance containing a methyl group attached to an imine.It can be written as CH 3 N=CH 2.On a timescale of minutes it self reacts to form the trimer trimethyl 1,3,5-triazinane.
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.
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 ...
It is a colorless liquid that is widely available. It is prepared by the reaction of dimethylamine and formaldehyde: [1] 2 (CH 3) 2 NH + CH 2 O → [(CH 3) 2 N] 2 CH 2 + H 2 O. It is used for the dimethylaminomethylation reactions, the reaction being initiated by the addition of a strong, anhydrous acid: [2] [(CH 3) 2 N] 2 CH 2 + H + → (CH 3 ...
DMAPA is commonly produced commercially via the reaction between dimethylamine and acrylonitrile (a Michael reaction) to produce dimethylaminopropionitrile. A subsequent hydrogenation step yields DMAPA: [2] DMAPA is readily converted to the mustard dimethylaminopropyl-3-chloride, a powerful alkylating agent. [3]

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.
