Industrial grade Trisodium phosphate 98% White crystal for chemical materials.

12 water trisodium CAS 10101-89-0 Industrial 98.5% Na₃O₄P·12H₂O

Molecular formula: Na₃PO₄·12H₂O

Molecular weight: 380.12

• Colorless acicular hexagonal crystal system
• Soluble in water, insoluble in organic solvents
• Relative density 1.62 (20°C)
• Melting point 73.3-76.7°C (decomposition)
• When weathered in dry air, 12 crystalline waters are lost at 100°C to form anhydrous substances (Na₃PO₄)
• The aqueous solution is alkaline and has a certain corrosive effect on the skin

Used as water softener in metallurgy, chemical industry, textile, printing and dyeing, paper making, mechanical and electrical industry, etc. Also used as:

• Boiler tube cleaning agent and detergent
• Metal rust prevention agent
• Fuel intermediate desiccant
• Sugar juice purification agent
• Photographic developer
• Fabric mercerizing enhancer
• Rubber milk coagulant
• Dental binder
• Pharmaceutical preparations

• Industrial grade (12 crystal water) TSP CAS 10101-89-0 98% Na₃O₄P·12H₂O
• Industrial grade (anhydrous) TSP CAS 7601-54-9 98% Na₃O₄P
• TSP CAS 7601-54-9 97% Na₃O₄P

1. Industrial cleaning and metal processing:

• Degreasing and oil removal: A 5% solution can remove grease from metal surfaces (with an efficiency 1.5 times that of NaOH)
• Metal phosphating: Compounded with zinc nitrate to form a dense phosphating film (film weight 2-4g/m²)
• Boiler scale removal: Dissolving silicate scale (SiO₂ dissolution rate > 90%)

2. Water treatment:

• Softener: Chelated Ca²⁺/Mg²⁺, hardness removal rate > 95%
• Corrosion inhibitor: Forms a protective film on the surface of carbon steel (corrosion inhibition rate ≥85%)
• Alkaline regulator: Maintains the pH of circulating water at 8.5-9.5

3. Washing and daily chemicals:

• Heavy scale detergent: Replace STPP, used as a detergent aid in phosphorus-free formulas
• Tableware machine cleaner: pH adjustment and suspended stains (Addition amount: 3-8%)

4. Other industrial applications:

• Textile printing and dyeing: Desizing agents, refining agents (increase the whiteness of cotton fibers by 20%)
• Ceramic industry: Glaze dispersant (reducing viscosity by 30%)
• equipment cleaning ( grade): Dedicated to CIP cleaning systems

• High-efficiency cleaning ability: The emulsification value (EAI) of oils and fats is ≥80% (superior to sodium carbonate). Dissolution rate of SiO₂ scale: The dissolution rate of a 10g/L solution at 80℃ is 1.2mm/h
• Environmental protection and economic efficiency: Biodegradable (degradation rate > 90% within 28 days). The cost of treating one ton of water is only $0.15 (saving 50% compared with organic scale inhibitors)
• Multi-form adaptation: Crystalline state: Readily soluble in cold water, suitable for rapid cleaning. Anhydrous powder: Easy to transport and store, suitable for high-temperature processes
• Compatibility compatibility: Synergistic effect with silicate and surfactant (35% increase in decontamination power)
