Phosphoric Acid Per Ton 2024

Phosphoric acid is a common inorganic acid with a chemical formula of H3PO4 and a molecular weight of 97.995. It 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. In the air, phosphoric acid is easy to deliquesce. When heated, it will lose water to obtain pyrophosphoric acid, and then further lose water to obtain metaphosphoric acid.

In industry, phosphoric acid can be used as a chemical raw material to form an insoluble phosphate film on the metal surface to protect the metal from corrosion. It can also be mixed with nitric acid as a chemical polishing agent to improve the smoothness of the metal surface. It can also be used to produce cleaning supplies. , phosphate esters, raw materials for pesticides, and raw materials for producing phosphorus-containing flame retardants. In the food industry, phosphoric acid is one of the food additives and can be used as a sour agent and yeast nutrient. 

Phosphoric acid also has its toxicity. High concentrations of phosphoric acid may cause chemical burns and eye irritation and pose a health hazard if inhaled or exposed. In addition, excessive phosphoric acid may also have a negative impact on the ecological environment by contaminating soil, water and air, leading to problems such as eutrophication of water bodies, algae blooms and algae blooms. Therefore, when using phosphoric acid, correct safety operating procedures should be strictly followed, and waste and residue should be properly handled and disposed of to ensure safety during use.
