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. [2] [3] Dimethylethylamine is a malodorous, volatile liquid at room ...
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%. An estimated 270,000 tons were produced in 2005.
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.

Dimethylethanolamine (DMAE or DMEA) is an organic compound with the formula (CH3)2NCH2CH2OH. It is bifunctional, containing both a tertiary amine and primary alcohol functional groups. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as a nootropic.
Dimethylaniline. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) N,N-Dimethylaniline (DMA) is an organic chemical compound, a substituted derivative of aniline. It is a tertiary amine, featuring a dimethylamino group attached to a phenyl group.
Dominic- Bighorn, 7.7 megatons. Operation Dominic was a series of 31 nuclear test explosions ("shots") with a 38.1 Mt (159 PJ) total yield conducted in 1962 by the United States in the Pacific. [1] This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958–1961 test moratorium.
e. In mathematics, Dirichlet's test is a method of testing for the convergence of a series. It is named after its author Peter Gustav Lejeune Dirichlet, and was published posthumously in the Journal de Mathématiques Pures et Appliquées in 1862. [1]
Series. In mathematical analysis, the alternating series test is the method used to show that an alternating series is convergent when its terms (1) decrease in absolute value, and (2) approach zero in the limit. The test was used by Gottfried Leibniz and is sometimes known as Leibniz's test, Leibniz's rule, or the Leibniz criterion.
