Orthophosphoric acid

Orthophosphoric acid



Applications:

1. Agriculture: Phosphoric acid is a raw material for the production of important phosphate fertilizers (calcium superphosphate, potassium dihydrogen phosphate, etc.), and is also a raw material for the production of feed nutrients (calcium dihydrogen phosphate);
2. Industry: Phosphoric acid is an important chemical raw material, the main functions are as follows:
1. Treat the metal surface and form an insoluble phosphate film on the metal surface to protect the metal from corrosion;
2. Mixed with nitric acid as a chemical polishing agent to improve the finish of the metal surface;
3. Raw material phosphates for the production of detergents and pesticides;
4. Raw materials for the production of phosphorus-containing flame retardants;
3. Food: Phosphoric acid is one of the food additives. It is used as a sour agent and yeast nutrient in food, and phosphoric acid is contained in cola. Phosphate is also an important food additive and can be used as a nutritional enhancer;
4. Medicine: Phosphoric acid can be used to prepare phosphorus-containing drugs, such as sodium glycerophosphate.



Precautions:

Production personnel should wear protective equipment when working, such as overalls, rubber gloves, rubber or plastic aprons, and long rubber boots. Pay attention to protect the respiratory organs and skin.
