Structure of sodium propionate, with methyl groups and H atoms omitted. [5] Color code: red = O, blue = Na. Anhydrous sodium propionate is a polymeric structure, featuring trigonal prismatic Na + centers bonded to six oxygen ligands provided by the carboxylates. A layered structure is observed, with the hydrophobic ethyl groups projecting into ...
The propionate / ˈ p r oʊ p i ə n eɪ t /, or propanoate, ion is C 2 H 5 COO −, the conjugate base of propionic acid. It is the form found in biological systems at physiological pH. A propionic, or propanoic, compound is a carboxylate salt or ester of propionic acid. In these compounds, propionate is often written in shorthand, as CH 3 CH ...
Calcium propionate and sodium propionate are effective against both B. mesentericus rope and mold. [ 9 ] Metabolism of propionate begins with its conversion to propionyl coenzyme A (propionyl-CoA), the usual first step in the metabolism of carboxylic acids.

A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.
Sodium dihydrogen phosphate Sodium hydrogen phosphate Trisodium phosphate. A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates. Most of these salts are known in both anhydrous (water-free) and hydrated forms ...
3-Hydroxypropionic acid is of interest as a bio-derived precursor to acrylic acid. [5]The polyester poly(3-hydroxypropionic acid) is a biodegradable polymer. [7] The method combines the high-molecular weight and control aspects of ring-opening polymerization with the commercial availability of the beta hydroxy acid, 3-hydroxypropionic acid which is abbreviated as 3-HP.
For example, when ethyl propionate with an oxygen-18 labeled ethoxy group is treated with sodium hydroxide (NaOH), the oxygen-18 is completely absent from the sodium propionate product and is found exclusively in the ethanol formed. [17] The reaction is often used to solubilize solid organic matter.
