What is Sodium Tripolyphosphate?
Sodium tripolyphosphate, often abbreviated as STPP, is a chemical compound with the molecular formula Na5P3O10. It is a white, crystalline powder or granular substance that is highly soluble in water. Sodium tripolyphosphate is widely used in various industries and applications. In the detergent industry, it serves as a builder, helping to enhance the cleaning efficiency of detergents by preventing the redeposition of dirt and maintaining water hardness. It is also used in water treatment to prevent scale formation in pipes and equipment. In the food industry, sodium tripolyphosphate is used as a preservative, pH regulator, and texture enhancer. Additionally, it finds applications in ceramic production, metal treatment, and other industrial processes.
Sodium Tripolyphosphate Uses
- Detergent Industry: This compound is commonly utilized as a builder or chelating agent in laundry and dishwashing detergents. It enhances cleaning efficiency by preventing dirt redeposition and eliminating hard water minerals.
- Water Treatment: This substance is applied in water treatment to counteract scale and deposits within pipes, boilers, and cooling systems. It helps maintain optimal efficiency in water heating and cooling equipment.
- Food Industry: Approved for use as a food additive, it finds application in various food processing tasks. It serves as a sequestrant, pH regulator, and texture enhancer in processed meats, seafood, dairy, and canned goods.
- Ceramic Industry: In ceramics, this compound serves as a dispersing agent and deflocculant. It improves the flow of ceramic slurries and reduces viscosity.
- Metal Treatment: Within metal cleaning and surface treatment, it acts as a dispersant and emulsifier in degreasers, rust removers, and plating baths.
- Other Industrial Uses: Its roles extend to multiple industrial processes, encompassing oil drilling, textiles, and paper production. It aids in dispersion, emulsification, and water hardness control.
Sodium Tripolyphosphate Structure
The structure of sodium tripolyphosphate (STPP) consists of three phosphate groups (PO4) linked together by oxygen atoms. Each phosphate group has a central phosphorus (P) atom bonded to four oxygen (O) atoms. The three phosphate groups are connected in a linear chain, forming a polyphosphate structure.
In sodium tripolyphosphate, sodium (Na) ions are associated with each phosphate group, balancing the charge of the polyphosphate structure. The sodium ions surround and stabilize the negatively charged phosphate groups.
The price of STPP can vary depending on factors such as the supplier, quantity, purity level, and market conditions. It is recommended to contact us directly to inquire about the current pricing for STPP. We will be able to provide you with accurate and up-to-date pricing information based on your specific requirements and location.
The chemical formula for sodium tripolyphosphate (STPP) is Na5P3O10. It indicates that each molecule of STPP contains five sodium ions (Na+) and three phosphate ions (P3O10^5-). The three phosphate ions are linked together by oxygen atoms to form a polyphosphate structure. The sodium ions balance the charge of the phosphate ions, resulting in a neutral compound.
