Propionic acid
Propionic Acid is an organic acid that naturally occars in the rumen, its purpose is to inhibit moulds, yeast and bacteria. Propionic acid is a linear monocarboxylic acid. It affords esters on reaction with alcohols or alkenes. It can be synthesized by reacting ethane, carbon monoxide and water. It participates as a precursor in the preparation of smallest azolium homoenolate intermediate. Propionic acid may be used in the synthesis of cellulose propionate (cellulose ester).

Propionic acid
Propionic acid is a water-soluble organic acid serving a range of applications. Propionic acid is used as a versatile preservative in food or feed industry. For bakery products it preserves as a proprionate. In animal feed applications, propionic acid preserves compound feed, grain or corn while reducing mold or yeast. In silage applications it improves fermentation. It also serves as a synthetic building block to produce pharmaceuticals, crop protection agents and solvents, as well as thermoplastics.
