Product Description

Hot sale Phosphoric acid H3po4 industry/food grade from supplier

Product Description

Phosphoric acid, also known as orthophosphoric acid, is a common inorganic acid with a chemical formula of H3PO4 and a molecular weight of 97.995. Phosphoric acid is not volatile, not easy to decompose, has almost no oxidizing properties, and has the properties of an acid. It is a three-basic weak acid. Its acidity is weaker than hydrochloric acid, sulfuric acid, and nitric acid, but stronger than acetic acid, boric acid, etc. Phosphoric acid deliquesces easily in the air. When heated, it will lose water to obtain pyrophosphoric acid, and then further lose water to obtain metaphosphoric acid. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as a rust inhibitor, food additive, dental and orthopedic, EDIC corrosive, electrolyte, flux, dispersant, industrial corrosive, fertilizer raw material and component for household cleaning products, and also Can be used as chemical reagent.

Application Areas

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

 

Storage and handling: Phosphoric acid should be stored in a cool, ventilated, dry place, away from fire sources and flammable items. Be careful when handling to avoid damage and leakage.
Protection during use: Wear protective gloves, glasses and protective clothing when handling phosphoric acid to avoid direct contact with skin and eyes.
Dilution and Mixing: When diluting or mixing phosphoric acid with other chemicals, do so slowly and avoid generating excessive heat or gas.
Avoid contact with certain substances: Phosphoric acid reacts violently with certain metals, oxides or bases and should be avoided.
Emergency treatment: If you accidentally come into contact with phosphoric acid or leakage occurs, flush with plenty of water immediately and seek medical help. At the same time, take appropriate measures to prevent fires and environmental pollution.
