Propionic acid

Propionic acid Product Description

【Product Introduction】

Propionic acid, also known as primary oleic acid, is a short-chain saturated fatty acid with the chemical formula CH3CH2COOH. It usually exists as a colorless, clear, oily liquid with an unpleasant rancid odor and is miscible with a variety of solvents such as water and ethanol. Propionic acid is mainly produced by chemical synthesis (such as propylene carbonyl synthesis) or fermentation.

【Product Features】

Good Chemical Stability
The molecular structure of propionic acid is stable. It is not easy to decompose or react chemically under common industrial and storage conditions such as room temperature (25℃) and normal pressure (101.325kPa), and can be stored for a long time.

Highly Effective Antibacterial Performance
Propionic acid and its salts can effectively inhibit the growth of various microorganisms such as mold and bacteria.

【Product Application】

Pharmaceutical Industry
In the pharmaceutical industry, propionic acid is often used as a solvent for drugs, especially in the preparation of injections, oral solutions and other dosage forms. As an acidic substance, propionic acid can effectively adjust the pH value of drugs and enhance the stability and solubility of drugs.

Food Industry
Propionic acid has significant antibacterial and antiseptic effects, and can effectively inhibit the growth of mold and bacteria, thereby extending the shelf life of food. In addition, propionic acid can also be used as a leavening agent for baked foods, such as bread and dough, to promote the expansion of dough and improve the taste and texture of food.

Industrial Application
Through esterification reaction, propionic acid can prepare organic ester compounds such as butyl propionate, which are widely used in synthetic flavors, coatings, plastics and other fields. In addition, propionic acid can also be used as a detergent for cleaning metal surfaces, glass, etc.
