Phosphoric acid CAS 7664-38-2

Phosphoric acid is also called orthophosphoric acid (molecular formula H3PO4). The pure product is a colorless, transparent, viscous liquid, odorless and very sour. Melting point 42.35℃, specific gravity 1.70, high boiling point acid, miscible with water in any ratio, boiling point 213℃ (lose 1/2 water), pyrophosphoric acid is generated. When heated to 300℃, it becomes metaphosphoric acid. Relative density 181.834. Easily soluble in water, soluble in ethanol.

Specification:

Application：

Chemical Industry:

One of the major uses of phosphoric acid is in the production of phosphate fertilizers, such as monoammonium phosphate (MAP) and diammonium phosphate (DAP). These fertilizers are crucial for agricultural productivity as they provide essential nutrients for plant growth.

Phosphoric acid serves as a starting material in the synthesis of various phosphate compounds used in different chemical applications.

Food Industry:

Phosphoric acid is used as an acidulant in the food industry, particularly in cola beverages and other soft drinks to provide a tangy flavor.

It is also used in the manufacture of processed foods to regulate acidity and improve shelf life.

Rust Removal and Metal Treatment:

Phosphoric acid is utilized as a rust converter. It reacts with rust (iron oxide) to form a black ferric phosphate coating, which can be easily removed.

It is used in metal pre-treatment processes such as passivation and phosphating to improve corrosion resistance and paint adhesion.

Dentistry and Orthodontics:

In dentistry, phosphoric acid is used as an etching solution to clean and roughen the surfaces of teeth before the application of dental fillings or sealants.

Detergents and Cleaning Agents:

It is an ingredient in some detergents and cleaning agents, particularly those designed for cleaning hard surfaces, removing mineral deposits, and descaling.

Water Treatment:

Phosphoric acid is employed in water treatment processes to prevent the formation of scale and to control the pH of water.

Pharmaceuticals:

In the pharmaceutical industry, phosphoric acid is used as an intermediate in the production of various medications and for adjusting the pH of solutions.

Electronic grade phosphoric acid：

Phosphoric acid is used in the manufacturing of semiconductors and in the etching process of integrated circuits.
