Product Description
Transparent colorless liquid Factory directly hydroxyphenoxy propionic
Propionic 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.

Function
Although there are many synthetic methods of propionic acid, there are only three methods to realize industrial production: Rapa method, propionaldehyde oxidation method and light hydrocarbon oxidation method. At present, only a small amount of propionic acid is produced by light hydrocarbon oxidation in China.

Potassium, sodium and calcium propionate can be used for the storage of bread aProfessional manufacturer propionic acid pricend cakes. 40% of its propionate dosage.
Transparent colorless liquid Factory directly hydroxyphenoxy propionic
The newly harvested grain contains water and is easy to rot and deteriorate during storage. Propionic acid has good effect in preventing mildew, rot and caking of grains.
Transparent colorless liquid Factory directly hydroxyphenoxy propionic
As a volatile liquid, propionic acid is continuously volatilized during feed storage, and the propionic acid vapor generated is in full contact with the feed surface, playing a uniform, extensive and efficient bacteriostatic effect. The results showed that propionic acid had good inhibitory effects on Aspergillus flavus, some aerobic bacillus, Salmonella and yeast.
