What is Propanoic Acid?

Propionic acid, whose Chinese name is propionic acid, is a colorless, pungent-smelling organic acid with a chemical formula of C3H6O2 and a CAS registration number of 79-09-4. Propionic acid is a short-chain fatty acid, a saturated monocarboxylic acid, with a carboxyl group (-COOH) connected to a propyl group (-CH2CH2CH3).

Propionic acid exists in small amounts in nature in some fermented products, such as cheese and bread during the fermentation process, and can also be produced in large quantities through biological fermentation or chemical synthesis. In industry, propionic acid is mainly used to produce propionate, propionate and other derivatives. These derivatives are widely used in plastics, rubber, food preservatives, feed additives, medicines, pesticides and other fields. Propionate is often used in food as a preservative to extend the shelf life of food, while propionate ester can be used as a plasticizer, adhesive and solvent.

In addition, propionic acid is an important component of animal nutrition and can be used as a feed additive to help promote the health of the animal’s digestive tract and improve feed utilization. In the field of medicine, propionic acid and its derivatives can be used as synthetic raw materials for certain drugs.

Propanoic Acid Uses

Food preservatives:
In the food industry, propionic acid and its sodium salt, calcium salt and other derivatives are used as preservatives, which can effectively inhibit the growth of mold and bacteria, thereby extending the shelf life of food. Mainly used for preservation and preservation of bread, pastries, cereal products, meat and dairy products.

Feed additives:
In the feed industry, propionic acid is used as a feed additive to improve the preservation quality of feed, inhibit the growth of mold in feed, and also helps to improve the digestive function of animals and improve feed conversion efficiency. It is widely used in poultry, pigs, ruminants, etc. Breeding industry.

Chemical production raw materials:
Propionic acid is an important raw material for the synthesis of propionate esters (such as methyl propionate, ethyl propionate, etc.). These esters can be used to produce chemical products such as plasticizers, adhesives, flavors and fragrances.
Propionic acid can also be further synthesized into acrylic acid, which is then used to produce high value-added chemicals such as acrylates and acrylamide. These chemicals are widely used in coatings, adhesives, textile treatment agents, paper coating agents, water treatment agents and other fields. .

Pharmaceutical and cosmetics industry:
In the field of medicine, propionic acid can be used as an intermediate in drug synthesis and used to prepare certain antibiotics, antiviral drugs and other pharmaceutical chemicals.
In cosmetics and personal care products, derivatives of propionic acid can be used as preservatives or pH adjusters to help maintain product stability and safety.

Agriculture and environmental protection:
Some derivatives of propionic acid can be used as fungicides and soil conditioners in agriculture, helping to control crop diseases and improve soil quality.
Propionic acid is also used in environmental protection, such as as a biodegradable disinfectant, sewage treatment agent, etc.

Other uses:
Propionic acid can be used as a solvent in the formulation of industrial products such as coatings, paints, and cleaners.
In leather, textile and other industries, propionic acid is used in leather tanning and textile finishing to improve product performance and appearance.

Propanoic Acid Advantages

Efficient anti-corrosion performance:
Propionic acid and its salts have good antibacterial and antiseptic properties and can inhibit a variety of molds and bacteria. They are especially outstanding in the fields of feed and food preservatives, which can effectively extend the shelf life of products and ensure food safety.

Propionic acid is an organic acid naturally present in some foods and fermentation products. It is biodegradable and has less impact on the environment than some traditional chemical preservatives.

Propionic acid is not only an excellent preservative, but can also be used as an intermediate in chemical synthesis. It is widely used in the production of various downstream products, such as propionate esters (such as methyl propionate, ethyl propionate, etc.). These ester products are widely used in It has important applications in plastics, rubber, coatings, adhesives and other industries.

Feed additive value:
In the feed industry, propionic acid and its salts are used as feed additives to improve feed quality, reduce the production of mycotoxins in feed, promote animal appetite and digestion and absorption, and improve feed conversion efficiency.

Safety and Regulatory Acceptance:
Propionic acid and its derivatives are approved for use as food preservatives in many countries and regions. Its safety and usage limits are clearly defined and comply with international food regulations and standards.

Reactivity and solubility:
Propionic acid has good chemical reactivity and solubility and can react with a variety of compounds to generate useful derivatives. It is also a good solvent and can dissolve a variety of organic and inorganic substances.

Environmentally friendly:
In certain environmental applications, propionic acid, as a biodegradable chemical, can be used in the production of biodegradable plastics and in the treatment of wastewater and soil, helping to achieve sustainable development goals.
