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 increasng 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. |
International development prospect of Sodium Tripolyphosphate
Sodium Tripolyphosphate (STPP) as an important chemical product,
its international development prospects are affected by many factors, including market demand,
environmental regulations, technological progress and so on.
The following is an analysis of its international development prospects:
1. Market demand
Detergent industry: Although the use of sodium tripolyphosphate
in detergents has decreased in developed countries due to environmental regulations,
market demand remains strong in developing countries due to its cost-effectiveness and efficiency.
Food Industry: With the growth of the global food processing industry,
the demand for sodium tripolyphosphate as a water retaining agent and quality improver is expected to remain stable.
Water treatment: With the attention of global water resources management,
sodium tripolyphosphate has a broad application prospect in water treatment,
especially in the field of industrial water treatment.
2. Environmental regulations
Restrictions and alternatives: In developed countries such as Europe and the United States,
strict environmental regulations limit the use of sodium tripolyphosphate in detergents,
and promote the development and promotion of environmentally friendly alternatives (such as zeolite, sodium citrate).
Developing countries: In developing countries with relatively loose environmental regulations,
the use of sodium tripolyphosphate is still relatively common,
but with the increase of environmental awareness, it may be gradually restricted in the future.
3. Technological progress
Production process improvement: Through technological innovation,
the production process of sodium tripolyphosphate may be more environmentally friendly
and reduce the impact on the environment.
Development of new alternatives: With the progress of science and technology,
more efficient and environmentally friendly alternatives will be developed
to gradually replace the application of sodium tripolyphosphate in some fields.
4. Regional market analysis
North America and Europe: Due to strict environmental regulations,
the market demand for sodium tripolyphosphate is gradually decreasing in these regions,
and the market share of alternatives is increasing.
Asia Pacific: Especially China and India, due to the rapid development of industrial
and food processing industries, sodium tripolyphosphate market demand is still large.
Latin America and the Middle East: Market demand in these regions is also growing,
especially in the water treatment and food processing sectors.
5. Future trends
Environmentally friendly products: With the increase of global environmental awareness,
the use of sodium tripolyphosphate may be further restricted in the future,
and more environmentally friendly alternatives will be developed and promoted.
Sustainable development: The chemical industry will pay more attention to sustainable development,
and the production and use of sodium tripolyphosphate will pay more attention
to environmental protection and resource conservation.
6. Challenges and opportunities
Challenges: Increasingly stringent environmental regulations, competition from alternatives,
and increasing production costs are the main challenges facing sodium tripolyphosphate.
Opportunities: In emerging markets, especially in Asia Pacific and Africa,
sodium tripolyphosphate still has a large market potential. In addition,
technological advances and process improvements also provide new opportunities
for the application of sodium tripolyphosphate.

4. Ceramic industry
Grinding aid: In ceramic production, sodium tripolyphosphate is used as a grinding aid
to help improve the grinding efficiency of raw materials.
Dispersant: It can also improve the fluidity of the slurry and improve product quality.
5. Textile industry
Washing aid: In textile processing, sodium tripolyphosphate is used as a washing aid
to help remove impurities from the fibers.
Bleaching stabilizer: It can also stabilize the bleaching process and improve the bleaching effect.
6. Paper industry
Dispersant: In the papermaking process, sodium tripolyphosphate is used as a dispersant
to help evenly disperse the fibers in the pulp.
Retention agent: It can also improve the retention rate of the filler and improve the quality of the paper.
7. Other applications
Cleaning agent: Sodium tripolyphosphate is used in various cleaning agents,
such as dishwashing detergent, hard surface cleaning agent and so on.
Industrial cleaning: In industrial cleaning, it is used to remove grease and dirt from metal surfaces.
8. Environmental protection and substitution
Environmentally friendly alternatives: Due to environmental problems,
the application of sodium tripolyphosphate in some fields is gradually replaced by environmentally friendly alternatives,
such as zeolite, sodium citrate and so on.
