| Material Notes | Aminating agent in the manuf. of ion-exchange resins for food processing Dimethylamine (DMA) is an organic secondary amine. It is a colorless, liquefied and flammable gas with an ammonia and fish-like odor. Dimethylamine is abundantly present in human urine. Main sources of urinary DMA have been reported to include trimethylamine N-oxide, a common food component, and asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide (NO) synthesis. ADMA is excreted in the urine in part unmetabolized and in part after hydrolysis to DMA by dimethylarginine dimethylaminohydrolase (DDAH). Statistically significant increases in urinary DMA have been found in individuals after the consumption of fish and seafoods. The highest values were obtained for individuals that consumed coley, squid and whiting with cod, haddock, sardine, skate and swordfish (PMID: 18282650). As a pure chemical substance Dimethylamine is used as dehairing agent in tanning, in dyes, in rubber accelerators, in soaps and cleaning compounds and as an agricultural fungicide. In the body, DMA also undergoes nitrosation under weak acid conditions to give dimethlynitrosamine.; Dimethylamine is a precursor to several industrially significant compounds. It reacts with carbon disulfide to give dimethyldithiocarbamate, a precursor to a family of chemicals widely used in the vulcanization of rubber. The solvents dimethylformamide and dimethylacetamide are derived from dimethylamine. It is raw material for the production of many agrichemicals and pharmaceuticals, such as dimefox and diphenhydramine, respectively. The chemical weapon tabun is derived from dimethylamine. The surfactant lauryl dimethylamine oxide is found in soaps and cleaning compounds. Unsymmetrical dimethylhydrazine, a rocket fuel, is prepared from dimethylamine.; Dimethylamine is an organic compound with the formula (CH3)2NH. This secondary amine is a colorless, flammable liquified gas with an ammonia- or fish-like odor. Dimethylamine is generally encountered as a solution in water at concentrations up to around 40%. In 2005, an estimated 270,000 tons were produced.; The molecule consists of a nitrogen atom with two methyl substituents and one proton. Dimethylamine is a base and the pKa of the ammonium salt CH3-NH2+-CH3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of 171.5 �C. Dimethylamine is produced by catalytic reaction of methanol and ammonia at elevated temperatures and high pressure: |
