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,N-Dimethylethylamine (DMEA), sometimes referred to as dimethylethylamine, is an organic compound with formula (CH 3) 2 NC 2 H 5.It is an industrial chemical that is mainly used in foundries as a catalyst for epoxy resins and polyurethane as well as sand core production.
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.
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.
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]
It undergoes directed ortho metalation with butyl lithium: [C 6 H 5 CH 2 N(CH 3) 2 + BuLi → 2-LiC 6 H 4 CH 2 N(CH 3) 2 LiC 6 H 4 CH 2 N(CH 3) 2 + E + → 2-EC 6 H 4 CH 2 N(CH 3) 2. Via these reactions, many derivatives are known with the formula 2-X-C 6 H 4 CH 2 N(CH 3) 2 (E = SR, PR 2, etc.).
Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide–based zwitterionic surfactant, with a C 12 (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. [4]
