Manufacturer of Industrial 85 Phosphoric Acid

Phosphoric acid or orthophosphate, chemical formula H3PO4, molecular weight 97.9724, is a common inorganic acid, is a strong acid. It can be obtained by dissolving phosphorus pentoxide in hot water. In orthophosphate industry, apatite is treated with sulfuric acid. Phosphoric acid is easily deliquescent in air. Pyrophosphoric acid can be obtained by heating, and then metaphosphoric acid can be obtained by further dehydration. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as antirust agent, food additive, dental and orthopedic surgery, EDIC corrosive agent, electrolyte, flux, dispersant, industrial corrosive agent, fertilizer raw materials and components household cleaning products. It can also be used as a chemical reagent. Phosphates are nutrients for all life forms.

Melting point: 42 C

Boiling point: 261 C (decomposition, phosphoric acid dehydration gradually by heating, so there is no boiling point of its own)
Phosphoric acid is a viscous concentrated solution containing 85% H3PO4. When crystallized from concentrated solution, the semihydrate 2H3PO4 H2O (melting point 302.3K) is formed.

Agriculture: Phosphoric acid is the raw material for the production of important phosphate fertilizers (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. Treat metal surface and form insoluble phosphate film on metal surface to protect metal from corrosion.

2. Mixed with nitric acid as a chemical polishing agent to improve the surface finish of metal surface.

3. Phosphate as raw material for the production of detergents and pesticides.

4. Raw materials for the production of phosphorus-containing flame retardants.
