Sodium Tripolyphosphate chemical structure
Physical and Chemical Properties of Sodium Tripolyphosphate
  • Chemical Formula: Na₅P₃O₁₀
  • Molecular Weight: 367.86 g/mol
  • Appearance: White crystalline or powdery solid
  • Form: Typically exists as an anhydrous compound (Na₅P₃O₁₀) or a hexahydrate (Na₅P₃O₁₀*6H₂O)
  • Water Solubility: Highly soluble in water, with solubility increasing with temperature
  • Other Solvent: Insoluble in organic solvents (e.g., ethanol)
  • Aqueous Solution pH: The pH of a 1% aqueous solution is approximately 9.5-10.5, making it alkaline
  • Decomposition Temperature: Decomposes at high temperatures (around 622°C)
  • Hydrate Stability: The hexahydrate tends to effloresce in dry air
  • Property: Strong hygroscopicity; easily absorbs moisture from the air
  • Property: STPP has strong chelating ability with metal ions
  • Application: Highly valuable in water treatment, detergents, and processing
Sodium Tripolyphosphate industrial application Sodium Tripolyphosphate production process
History of Sodium Tripolyphosphate

Sodium Tripolyphosphate (STPP) is an important chemical product, widely used in detergent, processing, water treatment and other fields.

1. Early Discovery and Development
  • Late 19th century: Chemical properties of phosphate were studied
  • Early 20th century: STPP was synthesized as a highly effective chelating agent
2. Industrial Production
  • Mid-20th century: Became key ingredient in detergent formulations
  • 1950s-1970s: Mass-produced worldwide for household and industrial detergents
3. Environmental Issues and Substitution
  • 1970s-1980s: Environmental concerns led to restrictions
  • Development of alternatives like zeolite and sodium citrate
4. Modern Applications
  • industry: Water retaining agent and quality improver
  • Water treatment: Corrosion inhibitor and scale inhibitor
  • Other industries: Ceramics, textiles, paper
5. Future Trends
  • Environmentally friendly alternatives
  • Technological innovation for more eco-friendly production
