Use and Manufacturing

1 DefinitionChEBI: A secondary aliphatic amine where both N-substituents are methyl.

2 Environmental FatePhotolytic. Dimethylnitramine, nitrous acid, formaldehyde, N,N-dimethylformamide and carbonmonoxide were reported as photooxidation products of dimethylamine with NOx. An additionalcompound was tentatively identified as tetramethylhydrazine (Tuazon et al., 1978). In theatmosphere, dimethylamine reacts with OH radicals forming formaldehyde and/or amides(Atkinson et al., 1978). The rate constant for the reaction of dimethylamine and ozone in theatmosphere is 2.61 x 10-18 cm3/molecule?sec at 296 K (Atkinson and Carter, 1984).Soil. After 2 d, degradation yields in an Arkport fine sandy loam (Varna, NY) and sandy soil(Lake George, NY) amended with sewage and nitrite-N were 50 and 20%, respectively. NNitrosodimethylaminewas identified as the major metabolite (Greene et al., 1981). Mills andAlexander (1976) reported that N-nitrosodimethylamine also formed in soil, municipal sewage,and lake water supplemented with dimethylamine (ppm) and nitrite-N (100 ppm). They found thatnitrosation occurred under nonenzymatic conditions at neutral pHs.Photolytic. Low et al. (1991) reported that the photooxidation of aqueous secondary aminesolutions by UV light in the presence of titanium dioxide resulted in the formation of ammoniumand nitrate ions.Chemical/Physical. In an aqueous solution, chloramine reacted with dimethylamine formingN-chlorodimethylamine (Isaac and Morris, 1983).Reacts with mineral acids forming water soluble ammonium salts and ethanol (Morrison andBoyd, 1971).
