Industrial Feed Grade 99.5 Min C3h6o2 Propionic Acid Price for Sale price

Propionic Acid, also known as Calcium Propionate, is a medium-strength carboxylic acid with the chemical formula C3H6O2 and molecular weight of 74.08 g/mol.Propionic Acid is a common organic compound with a variety of industrial and medical applications.
Chemical Properties and Preparation Methods
Propionic acid can be prepared by a variety of methods, including phytoextraction from acetoethanol, direct oxidation reaction of ethyl nitrate, and ethylene hydrocarboxylation. In addition, propionic acid can also be produced by biotechnological methods. Industrially, propionic acid is mainly produced by ethylene hydrocarboxylation using nickel carbonyl as a catalyst.
Industrial applications
Propionic acid has a wide range of industrial applications, mainly including:
Food preservatives: propionic acid can stop the growth of bacteria and extend the shelf life of food. It is commonly used in cheese, baked goods, soft drinks, fruit juices and canned goods.
Feed additives: Propionic acid and its ammonium salt are used as preservatives in animal feeds, accounting for about half of the world's propionic acid production.
Other uses: Propionic acid is also used as an antimicrobial agent, insecticide, and in the production of leather, dyes and paints.
Medical Applications
Propionic acid also plays an important role in the treatment of mental illness and autism, improving mood, cognitive function, and reducing maladaptive behaviors and symptoms of depression, etc.1 In addition, calcium propionate is approved for use by the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) as being virtually non-toxic to the human body, and it is commonly used as a preservative for food and feed. 

P ropionic acid is an important chemical raw material. Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices.
The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst.
