Product Details


Sodium Tripolyphosphate (STPP) Plant

Product Name: sodium tripolyphosphate

Molecular formula: na5p3010

Molecular weight: 367.86

Performance characteristics: white granular or powdery, performance density 0.35-0.90g/cm3, melting point 622 ℃. It is easy to dissolve in water, the aqueous solution is alkaline, and the pH of 1% aqueous solution is 9.7. It is hydrolyzed to phosphite gradually in water and has good ability of complexing metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. It can soften hard water. As an inorganic surfactant, it has some properties of organic surfactant.

Application: mainly used as additive of synthetic detergent, soap synergist and preventing soap synergist and preventing soap grease from precipitation and frost. It has strong emulsifying effect on lubricating oil and can be used to adjust pH value of buffer soap.


The STPP preparation process by Sodium Tripolyphosphate Plant is composed of three steps: preparation of phosphoric acid from phosphate rocks, sodium pyrophosphate from neutralization of the acid, and finally the formation of STPP by condensation and polymerization of the sodium pyrophosphate.
