Strong Alkalinity for High Cleaning Efficiency：Forms a highly alkaline solution (pH ≈ 11.5), making it very effective for degreasing, cleaning, and pH adjustment applications.
Excellent Water Solubility：Readily dissolves in water at room temperature, allowing fast preparation of concentrated alkaline solutions for industrial and processing use.
Stable Hydrated Crystal Structure：Retains part of its crystallization water even at elevated temperatures, ensuring good thermal stability and reliable performance during heating and storage.
High Purity Crystalline Form：White to colorless hexagonal crystals provide consistent quality, easy handling, and suitability for precise formulation and dosing.
Product Description of Trisodium Phosphate CAS#7601-54-9
Trisodium Phosphate Dodecahydrate is white to colorless hexagonal crystals with a density of about 1.62 g/cm³. It melts near 75 °C on rapid heating and partially loses crystal water at 100 °C, retaining the last water molecule even at higher ignition temperatures. Freely soluble in water with solubility of around 28 g/100 mL at 20 °C, forming a strongly alkaline solution; 0.1 M aqueous solution pH approx 11.5. Insoluble in alcohol, widely applied where strong alkalinity and good water solubility are required.
Product Application of Trisodium Phosphate CAS#7601-54-9
Trisodium Phosphate is an inorganic salt, widely used as high-efficiency industrial detergent, metal surface treatment agent and floor cleaner, featuring strong cleaning and degreasing performance. It also serves as a water softener and boiler water treatment chemical, and acts as a paint remover for surface preparation. Besides, it is applied in photographic developers, leather tanning, papermaking and sugar clarification, with versatile uses across various industrial processes.
