Chemical Materials Water Soluble Sodium Tripolyphosphate STPP For Industrial Waste Water Disposal

Molecular formula: Na5P3O10

Molecular weight: 367.86

Industrial grade CAS: 7758-29-4

Industrial grade products & COA meets GB/T 9983-2004 standard:

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.

Detergent industry:

• Current situation: Sodium tripolyphosphate used to be the main detergent aid, but because it may lead to eutrophication of water, many countries and regions have implemented phosphorus restriction policies.
• Trend: Phosphorus free or low phosphorus detergents are gradually becoming mainstream, and the use of sodium tripolyphosphate in detergents will gradually decrease.
• Opportunities: In areas where phosphorus is not yet strictly limited (such as some developing countries), sodium tripolyphosphate still has a certain market demand.

Food Industry:

• Status: Sodium tripolyphosphate as a food additive (E451) is used in meat, seafood and other products for water retention and texture improvement.
• Trend: As consumer concerns about food safety increase, the development of natural alternatives may reduce reliance on sodium tripolyphosphate.
• Opportunity: Under the premise of compliant use, sodium tripolyphosphate still has a stable market demand in food processing.

Industrial Water treatment:

• Current situation: Sodium tripolyphosphate is used to prevent scale and corrosion, and plays an important role in industrial water treatment.
• Trend: The research and development of environmentally friendly water treatment agents may have a certain impact on its market share.
• Opportunities: In specific industrial areas (such as high temperature and high pressure environments), sodium tripolyphosphate still has irreplaceable advantages.

Environmental pressure:

• The decomposition of sodium tripolyphosphate in the water body may lead to eutrophication, causing excessive algal reproduction and destroying the ecological balance.
• Worldwide, restrictions on phosphorus-containing products have been gradually strengthened to promote the development and application of phosphorus-free alternatives.

Green alternatives:

• The application of environmentally friendly detergent such as zeolite and polycarboxylate gradually replaced sodium tripolyphosphate in detergent.
• In the food industry, the development of natural water retaining agents and texture improvers may reduce reliance on sodium tripolyphosphate.

• Production process optimization: By improving the production process, the energy consumption and pollution in the production process of sodium tripolyphosphate can be reduced, and its environmental protection can be improved.
• Develop high value-added sodium tripolyphosphate derivative products and expand its application fields.

Exploration of new application fields:

• In the field of new energy and new materials, explore new uses of sodium tripolyphosphate, such as battery materials, catalysts and other applications.

Developed countries:

• Environmental regulations are strict, the use of sodium tripolyphosphate is greatly restricted, and the market demand is gradually declining.
• The market share of phosphorus-free or low-phosphorus alternatives continues to expand.

Developing countries:

• Environmental regulations are relatively loose, and sodium tripolyphosphate still has a large market demand in detergent, food and other fields.
• With increased environmental awareness, there may be a gradual transition to phosphorus-free alternatives in the future.

• Environmentally friendly sodium tripolyphosphate: Develop low- or phosphorus-free sodium tripolyphosphate alternatives to meet environmental requirements.
• Through technical improvement, the impact of sodium tripolyphosphate on the environment can be reduced.
• High value-added products: Develop sodium tripolyphosphate products with high purity and special functions to meet the needs of the high-end market.
• Expand its application in new energy, new materials and other fields.
• Circular economy: Reduce resource waste and environmental pollution by recycling and reusing sodium tripolyphosphate.
