Product Description

Famous manufacurer  Golden supplier  propionic acid 

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.

Application
Propionic acid has a wide range of uses. It can be used in the food industry to produce preservatives such as calcium propionate and sodium propionate, and can also be used to produce propionate ester flavors and fragrances. Pharmaceutical intermediates of pesticides and preservatives for green feed can also be used.
