Physicochemical Property
| Molecular weight: 163.94 g/mol | Appearance: white crystalline or powdery solid. |
| Odor: Odorless or slightly sulphide odor. | Density: 1.62 g/cm³ (dodecahydrate, 20°C). |
| Melting point: approx. 73.4°C (dodecahydrate decomposition). | Chemical Safety: Unrestricted goods |
Solubility: Water: easily soluble in water, aqueous solution is strongly alkaline (pH about 12); Organic solvent: insoluble in ethanol, and other organic solvents.
Hydrolysis reaction: Fully ionized in water to form phosphate ions and sodium ions
Complexation: Form an insoluble precipitate with metal ions (e.g. Ca² +, Mg² +) for softening hard water.
Thermal stability: It decomposes when heated to high temperatures, forming sodium phosphate and oxygen.
Acid base: The aqueous solution is strongly basic and can react with acid to form phosphate.
Industrial Applications
- Agriculture: As a high-efficiency phosphorus and potassium compound fertilizer, suitable for various crops, especially during flowering and fruiting periods to promote fruit expansion, color transformation, and improve crop stress resistance.
- Industry: Used as a quality improver, leavening agent, and fermentation aid in baked goods, beverages, and dairy products to adjust pH value and improve taste.
- Pharmaceutical Industry: Used in drug production, particularly for phosphorus and potassium supplements, and as buffers to regulate drug pH values.
- Chemical Industry: Functions as a buffer in chemical production to adjust reaction system pH values, commonly used in electroplating, dyes, and detergents. Also serves as a flame retardant component in plastics and rubber.
- Water Treatment: Used as a corrosion inhibitor to prevent pipe and equipment corrosion while regulating water pH.
- Step Lab: Serves as a standard reagent for buffer solutions in biochemical experiments and molecular biology research.
