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.

The development prospect of Sodium Tripolyphosphate in Europe
1. Regional market characteristics
Western Europe: the most stringent environmental regulations, the use of sodium tripolyphosphate is greatly limited,
and the market share is gradually replaced by alternatives.
Eastern Europe: Environmental regulations are relatively relaxed,
and the use of sodium tripolyphosphate is high, but with the gradual implementation of the EU environmental policy,
it may be more restricted in the future.
2. Future trends
Environmentally friendly products: With the increase of environmental awareness,
the use of sodium tripolyphosphate will be further reduced, and more environmentally friendly alternatives will be promoted.
Sustainable development: The European 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.
3. Challenges and opportunities
Challenge:
Increasingly stringent environmental regulations have restricted the use of sodium tripolyphosphate.
Increased competition from alternatives could affect their market share.
Chance:
In specific areas such as water treatment and food processing,
sodium tripolyphosphate still has a certain market demand.
Technological advances and process improvements provide new opportunities
for environmentally friendly applications of sodium tripolyphosphate.
Sum up
The development prospects of sodium tripolyphosphate in Europe are strictly limited by environmental regulations,
and its use has been significantly reduced in areas such as detergents,
and its market share has been gradually replaced by environmentally friendly alternatives.
However, in certain areas such as food processing and water treatment,
sodium tripolyphosphate still has a certain market demand. In the future,
with the enhancement of technological progress and environmental awareness,
the application of sodium tripolyphosphate will pay more attention to environmental protection and sustainable development.

Use of Sodium Tripolyphosphate

1. Water treatment
Scale inhibitor: used to prevent the formation of scale in boilers, cooling towers and pipelines
to extend the service life of equipment.
Corrosion inhibitor: Prevents corrosion of pipes and equipment by binding to metal ions.
Water softening agent: chelate calcium and magnesium ions in water, soften water quality,
and improve the efficiency of industrial water use.
2. Textile industry
Washing agent: Used to clean fibers, remove impurities and oils.
Bleaching stabilizer: stabilizes the role of bleaching agent in the bleaching process and improves the bleaching effect.
Dyeing auxiliaries: help dye evenly disperse, improve dyeing quality.
3. Paper industry
Dispersant: used to disperse the fibers in the pulp to improve the uniformity and strength of the paper.
Retention agent: Helps fillers and fine fibers distribute evenly in the paper, improving the quality of the paper.
4. Ceramic industry
Grinding aid: improve the grinding efficiency of raw materials and reduce energy consumption.
Dispersant: improve the fluidity of ceramic slurry, improve product quality.
