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).
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.
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.
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
Ammonium chloride, under the name sal ammoniac or salmiak is used as food additive under the E number E510, working as a yeast nutrient in breadmaking and as an acidifier. [31] It is a feed supplement for cattle and an ingredient in nutritive media for yeasts and many microorganisms.
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]
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 ...
