Information on Sodium Tri Polyphosphate
Sodium Tri Polyphosphate is a derivative of Phosphoric Acid. Sodium Tri Polyphosphate is moderately soluble in water. Sodium Tri Polyphosphate is a white crystalline powder. Sodium Tri Polyphosphate decomposes at 622oC. It should be stored in tightly closed containers in a Room Temperature.
Synthesis / Manufacturing Process of Sodium Tri Polyphosphate
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 Tri Polyphosphate is manufactured by heating stoichiometric mixture of Disodium Phosphate & Monosodium Phosphate under controlled conditions.
