Phosphoric acid

Molecular formula	H₃PO₄
CAS No.	7664-38-2
Specification	75%, 80%, 85% industrial grade phosphoric acid; 75%, 80%, 85% food grade phosphoric acid
Use	Agriculture: Phosphoric acid is the raw material for the production of important phosphate fertilizers (superphosphate, potassium dihydrogen phosphate, etc.), as well as the raw material for the production of feed nutrients (calcium dihydrogen phosphate). Industry: Phosphoric acid is an important chemical raw material, and its main functions are as follows: 1. Treat the metal surface to form a thin film of insoluble phosphate on the metal surface to protect the metal from corrosion. 2. Mixed with nitric acid as a chemical polishing agent to improve the smoothness of the metal surface. 3. Phosphate esters as raw materials for the production of detergents and pesticides. 4. Raw materials for the production of phosphorus-containing flame retardants. Food: Phosphoric acid is one of food additives. It is used as a sour agent and yeast nutrient in food. Coca-Cola contains phosphoric acid. Phosphate is also an important food additive and can be used as a nutritional enhancer. Medicine: Phosphoric acid can be used to prepare phosphorus-containing drugs, such as sodium glycerophosphate.
