Brief Overview

Tetrapotassium Pyrophosphate, also known as TKPP, appears as a white powder with high solubility in water. It is widely used in a broad range of industrial applications.  

Manufacturing Processes

Tetrapotassium Pyrophosphate is manufactured through neutralization and calcination reaction between phosphate and potassium hydroxide. Tetrapotassium Pyrophosphate, in the form of white crystalline powder, is obtained at the end of the process after the product is left to cool and crystallize.

H3PO4 + 2KOH → K2HPO4 + 2H2O 2K2HPO4 → K4P2O7 + H2O
