The DMACA is any of a number of acidified DMACA solutions: 0.117 g of DMACA, 39 mL of ethanol, 5 mL of conc hydrochloric acid and diluted to 50mL with water [1] 1 g DMACA, 1 mL conc. hydrochloric acid and 99 mL water [2] 1 g DMACA in 99 mL conc. hydrochloric acid. [3]
2 C 6 H 5 NH 2 → (C 6 H 5) 2 NH + NH 3. It is a weak base, with a K b of 10 −14. With strong acids, it forms salts. For example, treatment with sulfuric acid gives the bisulfate [(C 6 H 5) 2 NH 2] + [HSO 4] − as a white or yellowish powder with m.p. 123-125 °C. [8] Diphenylamine undergoes various cyclisation reactions.
2,4,6-Tris(dimethylaminomethyl)phenol is an aromatic organic chemical that has tertiary amine and phenolic hydroxyl functionality in the same molecule. [1] The formula is C 15 H 27 N 3 O and the CAS Registry Number is 90-72-2. It is REACH registered and the European Community Number is 202-013-9. [2] [3] [4]
DMA was first reported in 1850 by the German chemist A. W. Hofmann, who prepared it by heating aniline and iodomethane: [3] [4] C 6 H 5 NH 2 + 2 CH 3 I → C 6 H 5 N(CH 3) 2 + 2 HI. DMA is produced industrially by alkylation of aniline with methanol in the presence of an acid catalyst: [5] C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2 H 2 O
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%.
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. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as a nootropic.
Aminonaphthalenesulfonic acids are compounds with the composition C 10 H 6 (NH 2)(SO 3 H), being derived from naphthalene (C 10 H 8) substituted by an amino and sulfonic acid groups. These compounds are colorless solids.
2-[2-(Dimethylamino)ethoxy]ethanol is an organic compound with the molecular formula C 6 H 15 NO 2 and is a liquid at room temperature. Dimethylaminoethoxyethanol is polyfunctional, having a tertiary amine , ether and hydroxyl functionality.
