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

1. Market demand
Detergent Industry: In developing countries, the market demand for sodium tripolyphosphate remains strong due

to its cost effectiveness and efficiency. Although its use is restricted in developed countries due

to environmental regulations, it is still widely used in emerging markets.

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: The global emphasis on water resource management

has driven the use of sodium tripolyphosphate in water treatment, especially in the field of industrial water treatment.

2. Environmental regulations
Developed countries: Strict environmental regulations in Europe and the United States

and other regions have limited the use of sodium tripolyphosphate in detergents,

promoting the development of environmentally friendly alternatives (such as zeolite, sodium citrate).

Developing countries: In regions with relatively loose environmental regulations,

the use of sodium tripolyphosphate is still common,

but may gradually be restricted in the future as environmental awareness increases.

Use of Sodium Tripolyphosphate

1. Detergent industry
Main ingredient: Sodium tripolyphosphate is the main ingredient in many household and industrial detergents due

to its excellent decontamination and water softening ability.

Function: It can effectively chelate calcium and magnesium ions in water, prevent scale formation,

and enhance the cleaning effect of detergent.

2. Food industry
Water retaining agent: In meat and seafood processing, sodium tripolyphosphate is used as a water retaining agent

to help retain the moisture of products and improve taste and texture.

Quality improver: It can also improve the water retention and stability of food, extend the shelf life.

3. Water treatment
Corrosion inhibitor: Sodium tripolyphosphate is used in water treatment systems as a corrosion inhibitor

to prevent corrosion of pipes and equipment.

Scale inhibitor: it can effectively prevent the formation of scale and maintain the efficient operation of the equipment.

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.
