Physical and Chemical Properties
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 food processing.
Market Outlook in America
The growth prospects of sodium tripolyphosphate (STPP) in the Americas are influenced by several key factors:
- Market demand: Stable demand in detergents, food processing, and water treatment industries
- Environmental regulations: Phosphorus restriction policies may limit STPP demand
- Technological progress: Production improvements and environmentally friendly technologies
- Competitive landscape: Increasing competition from alternatives
- Economic environment: Growth and raw material price fluctuations affect market
Future outlook: Short-term demand remains stable, but long-term market share may decline with environmental requirements.
Applications
- Detergent industry: Key ingredient in detergents as water softener and dispersant
- Food processing: Used as preservative and quality improver in meat products
- Water treatment: Prevents scale formation in industrial and municipal systems
- Ceramic industry: Slurry dispersant for improved product quality
- Petroleum industry: Drilling fluid additive for viscosity control
- Textile industry: Dyeing aid for improved color uniformity
- Other applications: Metal surface treatment, paper industry, and more
