Propionic Acid Applications
Propionic acid is an organic synthesis raw material, primarily used to produce propionates and esters.
Its calcium and sodium salts serve as excellent preservatives for baked goods and grains.
Its esters are used as specialty solvents in fragrances and coatings.
Phenylmercuric propionate is an effective fungicide for coatings.
Propionic acid is also used as an additive in silage feed, among other applications.
