Disodium Di-Hydrogen Pyrophosphate, Disodium Di-Phosphate or Sodium Acid Pyrophosphate (SAPP) - Anhydrous
Grades We Manufacture :
Sodium Acid Pyrophosphate Anhydrous Industrial Grade
Formulation :
- 2H3PO4 + 2NaOH = Na2H2P2O7 + 3H2O
- 2H3PO4 + Na2CO3 = Na2H2P2O7 + CO2 + 2H2O
Sodium Acid Pyrophosphate also known as Di-sodium Di-phosphate is an inorganic compound of sodium and pyrophosphate. It is white and soluble in water. SAPP is manufactured with double drying process like other Pyrophosphates due to heating needed at a high temperature.
Application :
- Sodium Acid Pyrophosphate is used in leather treatment to remove iron stains
- Sodium Acid Pyrophosphate is widely used globally in food industry for baking reaction purpose
- SAPP is also used to stabilize the solution of hydrogen peroxide against reduction
- SAPP is used in petroleum industry as a dispersant in oil well drilling muds
- SAPP also has a wide use in dairy and poultry processes
