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 ...
In the toxicological literature, naturally occurring tetramethylammonium (anion unspecified) is often referred to by the name "tetramine". Unfortunately, this non-systematic or "trivial" name is also used for other chemical entities, including a toxic rodenticide (Tetramethylenedisulfotetramine).
The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
a fat-soluble organic compound that is primarily used as an antioxidant food additive: n-Butyllithium: an organolithium reagent; used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS) Carbon disulfide: a non-polar solvent; used frequently as a building block in organic chemistry
Illustrative is the preparation of tetramethylammonium fluoride: [6] NMe 4 + OH − + HF → NMe 4 + F − + H 2 O. Solutions of TMAH may be used to make other tetramethylammonium salts in metathesis reactions with ammonium (NH 4 +) salts. For example, tetramethylammonium thiocyanate may be prepared from ammonium thiocyanate as follows: [7]
In 1990, the Food and Drug Administration (FDA) banned the use of red dye No. 3 in cosmetics due to studies that linked high doses of the additive to thyroid cancer in animals. However, it was ...
