| Use | propionic acid is widely used in the food industry for the production of calcium propionate, sodium propionate and other preservatives, it can also be used for the production of propionate flavor. used as organic reagents, esterifying agents and plasticizers, also used in the preparation of food spices preservatives; Fungicides; Spices. A viscous substance inhibitor for beer and the like. as a feed fungicide. Dosage: 0.15%-0.25%. propionic acid is an important chemical raw material, is the fungicide metalaxyl, benzalene, herbicide dimefter, quetiapine, haizole, piroxobin, thiazolium, flupirheeling, it is also an intermediate of medicine and can be used as a preservative in food industry and a preservative for green feed. 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 home Medicine, Medicine, spices and so on. In grain and feed additives, the application effect of propionic acid is remarkable, and the consumption is increasing rapidly. (1) food additives. Calcium propionate and sodium propionate can prevent food spoilage caused by the action of microorganisms, prolong food storage time, effective for the preservation of bread and cakes. (2) grain preservative. Propionic acid has been successfully used in the prevention of mildew and caking of cereals, which provides a new method for the long-term storage and preservation of cereals. (3) beverage preservation agent. It is proved that propionic acid, sodium propionate and calcium propionate are all good feed preservatives, which are mostly used to preserve feed for pigs, cattle, sheep and poultry, among which calcium propionate has the best effect. Zinc propionate and cadmium propionate in propionic acid salt are the catalyst for producing terephthalate polyester; There are many varieties of propionate esters, with their respective uses, which can be used as solvents, fragrances, pharmaceutical intermediates, cosmetic additives, resin modifiers, cigarette filter plasticizers, gas oil antiknock agents, antibacterial agents and so on. Propionic acid derivatives of the intermediate 2-chloropropionic acid, lactic acid, 2, 2-dichloropropionic acid, 2-bromopropionic acid, 3-chloropropionic acid, propionitrile, propionyl chloride, respectively, for many drugs, pesticides, production of spices and other products. for the preparation of flavor propionate, and used as nitrocellulose solvent and plasticizer, etc. Food preservative intermediates; For esterification reaction; For the modification of alkyd resin; for the production of synthetic lubricants and hydraulic fluids. determination of aromatic diamines, gas chromatography analysis standard. Insect cell culture grade is used to inhibit the growth of mold in insect cell culture. |
