Sodium propionic acid salt compound

Product details      Propionic acid, also known as primary oleic acid, is a short-chain saturated fatty acid with the chemical formula CH3CH2COOH. Its molecular weight is 74.08 and the number of covalent bond units is 1. Propionic acid is a weak electrolyte (pKa = 4.87 at 25°C), and its aqueous solution is weakly acidic. However, it is highly corrosive and its vapor is irritating to the skin and respiratory tract. At normal temperature and pressure, propionic acid is a colorless clear oily liquid with a pungent and unpleasant rancid odor. Its melting point is -24 to -23 °C, its boiling point is 141.7 ± 3.0 °C, its flash point is 51.7 ± 0.0 °C, and it can be miscible with water, ethanol, chloroform, and ether. Its vapor can form an explosive mixture with air. Storage should be done in a cool and ventilated place, away from fire sources, and isolated from oxidants.    Propionic acid is mainly used as a food preservative and anti-mildew agent, especially suitable for the preservation of…
