Sodium propanoate or sodium propionate is the sodium salt of propionic acid which has the chemical formula Na(C 2 H 5 C O O).This white crystalline solid is deliquescent in moist air.
Preparation of 3-phenylpropionic acid. Then the solution is cooled, and freshly prepared 2.5 % sodium amalgam is added slowly in small pieces with efficient stirring. After consumption of about 300-350 g of sodium amalgam alloy, a sample of the solution is treated with hydrochloric acid and then again with sodium hydroxide solution.

What is the pH of a 0.38 M solution of sodium propionate, NaC3H5O2, at 25 degrees celcius? (For propionic acid, HC3H5O2, Ka = 1.3 x 10^-5 at 25 degrees celcius.) pH of the Solution:
Bookmark not defined.,9,10 Propionic acid is mainly used as a preservative in stored animal feed and grain. It is technically a fungicide (molds) and bactericide. Over 75% of propionic acid used for this purpose is in the form of the salt, ammonium propionate, because it is less corrosive to farm equipment.
3-(methylthio)propionic acid is a thia fatty acid acid consisting of propionic acid with a methylthio substituent at the 3-position; an intermediate in mammalian methionine metabolism in vitro. The simplest known phytotoxin, it is a blight-inducing toxin produced by the cassava pathogen Xanthomonas campestris manihotis.
Industrial uses. Propionic acid inhibits the growth of mold and some bacteria at the levels between 0.1 and 1% by weight. As a result, most propionic acid produced is consumed as a preservative for both animal feed and food for human consumption. For animal feed, it is used either directly or as its ammonium salt.
Alkali salts are prepared by contacting 2,2-dichloropropionic acid with an essentially dry alkali compound of an alkali metal in a liquid chlorinated hydrocarbon as a reaction medium, and thereafter separating in its solid phase an alkali salt of 2,2-dichloropropionic acid.
