Propionic acid is an important chemical raw material, is a fungicide armor frost spirit, benzene frost spirit, herbicide stam, main grain spirit, well, pyrazole fluorine grass grass spirit spirit, thiazole grasses spirit, milk fluorine chlorine, fluorine pyrazole grain spirit spirit grass, grass amine c, such as the enemy grass amine intermediates, pharmaceutical intermediates, and can be used as food preservative, the green food antistaling agent and so on.

Propionic acid is an important fine chemical and an intermediate of many other fine chemicals.It is mainly used as food and feed additives, followed by household herbs and herbs, medicine, spices, etc. In grain and feed additives, the application of propionic acid is significant, the consumption growth is rapid.(1) food additive. Calcium propionate and sodium propionate can prevent food spoilage caused by microbial action, prolong food preservation time, and be used for bread and cake preservation effectively.(2) grain preservatives. Propionic acid was successfully used to prevent mildew and agglomeration in grain, which provided a new method for long-term storage and freshness preservation of grain.(3) beverage preservation agent. The results show that calcium propionate, sodium propionate and calcium propionate are all good forage preservation agents.Zinc propionate and cadmium propionate in propionic acid salts are catalysts for the production of terephthalates. A wide variety of propionic acid esters, have their USES, as a solvent, spices, pharmaceutical intermediates, cosmetic additives, resin modifier, cigarette filter tip plasticizer, gas oil, dope, antibacterial agent, etc. Propionic acid derivatives intermediates 2 - chloropropionic acid, lactic acid, 2, 2-2 chloropropionic acid, 2 - bromine propionic acid, 3 - chloropropionic acid, acrylic nitrile, propionyl chloride, were used for many drugs, pesticides, herbicides, food fortifier, spices and other products.
