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
The development prospect of Sodium Tripolyphosphate (STPP) in Asia is influenced by
many factors such as economic growth,
industrialization, environmental protection policies and market demand in the region.
The following is a detailed analysis of its prospects in Asia:
1. Market demand
Detergent industry: With a large population in Asia and a large
demand for detergents,
especially in developing countries (such as India, Indonesia, Vietnam, etc.),
sodium tripolyphosphate is still widely used as an efficient and economical detergent ingredient.
Food processing: With the rapid development of the food processing industry in Asia,
the demand for sodium tripolyphosphate as a water retaining agent and quality improver continues to grow,
especially in the meat and seafood processing fields.
Water treatment: The industrialization process in Asia is accelerating,
the demand for industrial water and sewage treatment is increasing,
and the application prospect of sodium tripolyphosphate in water treatment is broad.
Other industries: The rapid development of textile, ceramics,
paper and other industries has also promoted the demand for sodium tripolyphosphate.
2. Impact of environmental protection policies
Restrictions in some countries: In some environmentally conscious
Asian countries (such as Japan and South Korea),
the use of sodium tripolyphosphate is restricted, especially in the field of detergents,
and is gradually replaced by environmentally friendly alternatives.
Loose policies in developing countries: In India, Southeast Asia and other regions,
environmental regulations are relatively loose, the use of sodium tripolyphosphate is still common,
but with the increase of environmental awareness, the future may gradually be restricted.
Sustainable development trend: Asian countries are gradually attaching importance to sustainable development,
and more stringent environmental protection policies may be introduced in the future
to promote the research and development and application of sodium tripolyphosphate substitutes.
3. Regional market characteristics
China: As the world's largest producer and consumer of sodium
tripolyphosphate,
China has a huge demand for sodium tripolyphosphate in the fields of detergents,
food processing and water treatment. However, with the tightening of environmental protection policies,
its use in detergents may be gradually reduced in the future.
India: The demand for sodium tripolyphosphate in the Indian market is growing rapidly,
especially in the detergent and food processing sectors,
but may face adjustment in the future due to environmental pressure.
Southeast Asia: The industrialization of Southeast Asian countries such as Vietnam
and Indonesia has accelerated, and the demand for sodium tripolyphosphate continues to grow,
especially in the field of water treatment and food processing.
Japan and South Korea: Japan and South Korea have strict environmental regulations,
and the use of sodium tripolyphosphate is gradually decreasing, relying more on environmentally friendly alternatives.
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.
