Sulfuric acid is the most abundant product of the chemical industry. It is used in the refining of metals and in the manufacture of a wide variety of substances. It is used for the pickling of steel to retard corrosion, in the refinement of petroleum, and in the manufacture of fertilizers.
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.ropionic acid is also useful as an intermediate in the production of other chemicals, especially polymers. Cellulose-acetate-propionate is a useful thermoplastic. Vinyl propionate is also used. In more specialized applications, it is also used to make pesticides and pharmaceuticals.
