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).
Ammonium chloride, ammonium sulfate, or ammonium phosphate may be used as sources of nitrogen. [ 11 ] [ 12 ] [ 13 ] [ 1 ] Phosphoric acid , an acidulant , is used as a yeast stimulant. [ 14 ] Calcium iodate, [ 15 ] an oxidant, [ 16 ] is a U.S. Food and Drug Administration generally recognized as safe source of calcium.
Tetrabutylammonium chloride is the organic compound with the formula [(CH 3 CH 2 CH 2 CH 2) 4 N] + Cl −, often abbreviated as [Bu 4 N]Cl, where Bu stands for n-butyl. A white water-soluble solid, it is a quaternary ammonium salt of chloride. It sees use as a phase-transfer catalyst, although it is less popular that the corresponding bromine ...
3. Using Ingredients at the Wrong Temperature. When you're baking and the recipe calls for room temperature or softened butter, you do in fact need to use room temperature butter.
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.
A flat cookie sheet. Because there are no sides on a cookie sheet, this baker used metal binder clips to keep the parchment baking paper from sliding off. Professional sheet pans used in commercial kitchens typically are made of aluminum, with a 25 mm (1 in) raised lip around the edge, and come in both standard and non-standard sizes. Within ...
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.
