Information on Diammonium Phosphate

Diammonium Phosphate is a derivative of Phosphoric Acid. Diammonium Phosphate is freely soluble in water. Diammonium Phosphate is a white crystalline powder with a melting point of 155^oC. It should be stored in tightly closed containers in a Room Temperature.

Synthesis / Manufacturing Process of Diammonium 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.

Diammonium Phosphate is manufactured by taking a reaction between Ammonia (NH3) and phosphoric acid (H3PO4). The resulting slurry of DAP is solidified in a granulator.
