Product Description

Information on Sodium Acid Pyro Phosphate

Sodium Acid Pyro Phosphate is a derivative of Phosphoric Acid. Sodium Acid Pyro Phosphate is moderately soluble in water. Sodium Acid Pyro Phosphate is a white crystalline powder with a melting point in excess of 600oC. It should be stored in tightly closed containers in a Room Temperature.

 

Synthesis / Manufacturing Process of Sodium Acid Pyro Phosphate

The major raw material to all the phosphates is Phosphoric Acid. Phosphoric Acid is manufactured from Rock Phosphate. Phosphate rock is fed to a series of reactors along with recycled phosphoric acid from the process.  The phosphoric acid-fluoroapatite slurry is mixed with sulphuric acid which is added to the reactor series as a leaching agent.  After completing the reaction series, the process stream is washed with evaporator condensate while being forced through a filter. The filter cake is composed primarily of gypsum (CaSO4 2H2O). The Phosphoric Acid is concentrated to 75-100% by a series of evaporators and then cooled.

Sodium Acid Pyro Phosphate is manufactured by taking a reaction between Sodium Carbonate & Phosphoric Acid, followed by heating of the resulting Sodium Phosphate at 220oC.
