Phosphoric acid

1. Molecular Formula: H3PO4
2. CAS Number: 7664-38-2
3. Specifications: 75%, 80%, 85% industrial grade phosphoric acid; 75%, 80%, 85% food grade phosphoric acid
4. Applications:
Agriculture: Phosphoric acid is a raw material for producing important phosphate fertilizers (such as calcium superphosphate, potassium dihydrogen phosphate, etc.) and also for manufacturing feed nutritional supplements (like calcium dihydrogen phosphate).
Industry: Phosphoric acid is a significant chemical raw material, with main uses as follows:
1. Treating metal surfaces to form insoluble phosphate films that protect metals from corrosion.
2. Mixed with nitric acid as a chemical polishing agent to improve the smoothness of metal surfaces.
3. Serving as a raw material for producing phosphates used in detergents and pesticides.
4. Acting as a raw material for manufacturing phosphorus-containing flame retardants.
Food: Phosphoric acid is one of the food additives, used as an acidulant and yeast nutrient in food products; for example, it is contained in Coca-Cola. Phosphates are also important food additives that can serve as nutritional enhancers.
Medicine: Phosphoric acid can be used to prepare phosphorus-containing drugs, such as sodium glycerophosphate, etc.
