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%.
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 ...
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]
Dimethylethanolamine (DMAE or DMEA) is an organic compound with the formula (CH 3) 2 NCH 2 CH 2 OH.It is bifunctional, containing both a tertiary amine and primary alcohol functional groups.
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]
The anions thus formed add to the formamidinium cations which in turn eliminate dimethylamine and react to form dimethylaminomethylene compounds (= CH−N(CH 3) 2) or amidines by aminomethyleneation.

Dimethylaminoethoxyethanol is manufactured by reacting dimethylamine and ethylene oxide. [2] Other methods are also available producing streams rich in the substance which then need to be further purified. [3]
[6] The LPGMA alleged that the FPI is a front of the Big 3, or the main three petroleum firms in the Philippines – Shell, Petron, and Chevron. [ 7 ] Their participation in the 2013 elections was challenged by the FPI which argued that retailers are not eligible to have partylist representation as per the Partylist Law or the 1986 Philippine ...
