Tetramethylammonium chloride is a major industrial chemical, being used widely as a chemical reagent [1] and also as a low-residue bactericide in such processes as hydrofracking. [2] In the laboratory, it has fewer synthetic chemical applications than quaternary ammonium salts containing longer N-alkyl substituents, which are used extensively ...
Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me 4 N] + and consists of four methyl groups ( −CH 3 , denoted Me) attached to a central nitrogen atom.
This is a list of CAS numbers by chemical formulas and chemical compounds, ... silver chloride: 7783–90–6 AgClO 3: silver chlorate: 7783–92–8
One of the earliest preparations is that of Walker and Johnston, [4] who made it by the salt metathesis reaction of tetramethylammonium chloride and potassium hydroxide in dry methanol, in which TMAH is soluble, but potassium chloride is not: NMe 4 + Cl − + KOH → NMe 4 + OH − + KCl. Where Me stands for the methyl group, –CH 3.
Tetraethylammonium chloride (TEAC) is a quaternary ammonium compound with the chemical formula [N(CH 2 CH 3) 4] + Cl −, sometimes written as [NEt 4]Cl. In appearance, it is a hygroscopic, colorless, crystalline solid.
An extensive study of the toxicology of tetraethylammonium chloride in mice, rats and dogs was published by Gruhzit and co-workers in 1948. These workers reported the following symptoms in mice and rats receiving toxic parenteral doses: tremors, incoordination, flaccid prostration, and death from respiratory failure within 10–30 minutes; dogs ...
