About 10 million tons of phosphoric acid, H3PO4, is produced annually in the United States. Most of the acid (about 80%) is used for agriculture, the rest (about 10%) is used as an additive in cleaners. Detergents, pesticides are used as animal feed additives. The rest (10%) is used orally (carbonated beverages). Industrial production method This acid is made by adding sulfuric acid to the stone. Phosphate is formed.
Phosphoric acid is one of the most widely used chemicals in the industry. As an additive in carbonated beverages, in the production of chemical fertilizers, soap and non-soap cleaners, water purification, animal feed and pharmaceuticals, livestock and poultry feed supplements (production of DC and calcium monophosphate phosphate), phosphate detergents, purifiers Production of phosphate fertilizers, fire retardant of some surfaces and inhibitors of ignition, as well as used for cleaning and scaling of metal surfaces.
Phosphoric acid or inorganic acid is called mineral acid, phosphoric acid.
Phosphoric acid is available in two types, industrial and edible, and phosphoric acid is a colorless, clear, odorless liquid with a pungent taste. Phosphoric acid is one of the most widely used chemicals in the industry.
Phosphoric acid production:
By adding sulfuric acid to phosphate, calcium or phosphate minerals are combined with sulfuric acid. In Iran, phosphoric acid is produced from the effect of sulfuric acid on apatite minerals
* It is due to combustion of phosphorus and hydration of P4O10. A mixture of liquid and air phosphorus is injected into a tower-like combustion chamber and produced by the oxidation reaction of phosphorus.
