Information on Disodium Phosphate
Disodium Phosphate is a derivative of Phosphoric Acid. Disodium Phosphate is moderately soluble in water. Disodium Phosphate is a white crystalline powder. Disodium Phosphate decomposes at 250oC. It should be stored in tightly closed containers in a Room Temperature.
Synthesis / Manufacturing Process of Disodium 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.
Disodium Phosphate is manufactured by taking a reaction between Sodium Hydroxide (NaOH) and phosphoric acid (H3PO4). The resulting slurry of DSP is solidified in a granulator.
