Use:
Agriculture use:raw material of phosphate fertilizerand feed nutrients
Industry use: chemical raw materials
1.Protect the metal from corrosion
2.Mixed with nitric acid as chemical polishing agentto improve the surface finish of metal
3.Material of phosphatide which is used for producewashing product and insecticide
4.The production of phosphorus containing flameretardant materials.
Food additives use:acidic flavoring,Yeast Nutri-ents, ,such as coca-cola.
Medical use:to produce medicine containing phos-phorus,such as Na 2 Glycerophosphat
Phosphoric acid, also known as orthophosphoric acid, is a common inorganic acid. It is a medium-strong acid with the chemical formula H3PO4 and a molecular weight of 97.995. Not volatile, not easy to decompose, almost no oxidation.
Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitors, food additives, dental and orthopaedic surgery, EDIC caustics, electrolytes, flux, dispersants, industrial caustics, fertilizers as raw materials and components of household cleaning products, and can also be used as chemical agents.
Agriculture: Phosphoric acid is a raw material for the production of important phosphate fertilizers (calcium superphosphate, potassium dihydrogen phosphate, etc.), and also for the production of feed nutrients (calcium dihydrogen phosphate).
Industry: Phosphoric acid is an important chemical raw material. Its main functions are as follows:
1, the treatment of metal surface, the formation of insoluble phosphate film on the metal surface, to protect the metal from corrosion.
2, mixed with nitric acid as a chemical polish, to improve the finish of the metal surface.
3, the production of washing supplies, insecticide raw material phosphate ester.
4, the production of raw materials containing phosphorus flame retardant.
Food: phosphoric acid is one of the food additives, in food as a sour agent, yeast nutrition agent, cola contains phosphoric acid. Phosphates are also important food additives and can be used as nutrient enhancers.
Medicine: Phosphoric acid can be used to make phosphorous drugs, such as sodium glycerophosphate.
