Food grade Phosphorous acid 85% CAS 7664-38-2 with factory price
Phosphoric acid, also known as orthophosphoric acid, is a common inorganic acid, is a strong acid, chemical formula H3PO4, molecular weight 97.995. Not volatile, not easy to decompose, almost no oxidation. With the commonness of acid, it is a ternary weak acid, and its acidity is weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc. Phosphoric acid delixes easily in air. Heat will lose water to pyrophosphoric acid, and further water loss to metaphosphate. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitor, food additive, dental and orthopaedic surgery, EDIC etchant, electrolyte, flux, dispersant, industrial etchant, fertilizer raw materials and components of household cleaning products, and can also be used as chemical reagents.

Usage:
Industry: Phosphoric acid is an important chemical raw material. Its main functions are as follows:
1, treat the metal surface, generate insoluble phosphate film on the metal surface to protect the metal from corrosion.
2, mixed with nitric acid as a chemical polish to improve the finish of the metal surface.
3, the production of washing supplies, pesticide raw material phosphate ester.
4, the production of phosphorus-containing flame retardant raw materials.
Food: Phosphoric acid is one of the food additives, in food as a sour agent, yeast nutrition, cola contains phosphoric acid. Phosphate is also an important food additive and can be used as a nutrient enhancer.
Medicine: Phosphoric acid can be used to make phosphorus-containing drugs, such as sodium glycerophosphate.
