Application

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.

Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the
chemical formula ch3ch2cooh. Propionic acid is a colorless, corrosive liquid with pungent smell.

Propionics acid is used in the productionof propionates used as mold inhibitors andpreservatives for grains and wood chips,
in the manufacture of fruit flavors and perfumebases, and as an esterifying agent.

Propionics acid is used as a mold inhibitor in bread and cheese products; in fungicides and herbicides;
preservative for grains and wood chips; in emulsifying agents; in solutions for electroplating nickel, perfume esters,
artificial fruit flavors, pharmaceuticals, and cellulose propionate plastics.

Propionics Acid is the acid source of the propionates. propionic acid in the liquid form has a strong odor and is corrosive,
so it is used as the sodium, calcium, and potassium salts as a preservative. these yield the free acid in the ph range of
the food in which they are used. it functions principally against mold. see calcium propionate; sodium propionate.

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature does not exceed 32ºC, and the relative humidity does not exceed 80%. Keep the container tightly closed.
