Molecular formula: Na5P3O10
Molecular weight: 367.86
Industrial grade CAS: 7758-29-4
Industrial grade products & COA meets GB/T 9983-2004 standard:
| Items for detecting and analyzing | Standard value |
|---|---|
| Main content: sodium tripolyphosphate ≥ | 96.0% |
| Phosphorus pentoxide P2O5≤ | 57.0% |
| Water insoluble≤ | 0.10% |
| Iron ≤ | 0.007% |
| Ph Value (1%) | 9.2-10.0 |
| Whiteness ≥ | 90 |
| 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. At 20°C, solubility is approximately 14 g/100 mL. At 60°C, solubility is approximately 30 g/100 mL |
| 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) into sodium pyrophosphate (Na₄P₂O₇) and sodium metaphosphate (NaPO₃) |
| Hydrate Stability | The hexahydrate tends to effloresce in dry air, losing its water of crystallization |
| Property | Strong hygroscopicity; easily absorbs moisture from the air and may form clumps |
| Property | STPP has strong chelating ability, forming stable soluble complexes with metal ions such as calcium, magnesium, and iron in water |
| Application | This property makes it highly valuable in water treatment, detergents, and processing |
