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).
a mineral acid with many industrial uses; commonly used in the laboratory preparation of hydrogen halides Phosphorus pentachloride: one of the most important phosphorus chlorides; a chlorinating reagent. Also used as a dehydrating agent for oximes which turn them into nitriles. Phosphorus tribromide: used for the conversion of alcohols to alkyl ...
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]
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.
Almost everything is used. Even so, the Swartzes’ financial situation feels precarious. They draw $3,890 a month from Social Security, along with $240 a month from two small pensions.
Britain's online safety regime came into force on Monday, requiring social media companies like Meta's Facebook and ByteDance's TikTok to take action to tackle criminal activity on their platforms ...
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.
