Description

General description

Propionic acid (PA) is a naturally occurring carboxylic acid, which in its pure state exists as a colorless corrosive liquid with an unpleasant odor. It is miscible in water. Industrially it is produced by hydrocarboxylation of ethylene in presence nickel carbonyl as a catalyst. PA has been found to reduce food intake, lower the fatty acids content in plasma and liver, might improve tissue insulin sensitivity and exerts immunosuppressive actions. Propionic acid is an excellent raw material as it is stable, cheap and safe and can even be used as a food additive.

Propionic acid is a volatile fatty acid (VFA) formed in the rumen of ruminants by bacterial fermentations.
