Physicochemical property
| Molecular weight: 611.77 g/mol | Appearance: White crystalline or powdery solid. |
| Odor: Odorless or slightly sulphide odor. | Density: 2.484 g/cm³ (25°C). |
| Melting point: about 616°C (decomposition). | Chemical Safety: Unrestricted goods |
| Solubility: Water: easily soluble in water, the aqueous solution is weakly alkaline (pH about 6-8); Organic solvent: insoluble in ethanol, and other organic solvents. |
| Hydrolysis reaction: It is gradually hydrolyzed in water to form orthophosphate |
| Complexation: Form a soluble complex with metal ions (e.g. Ca² +, Mg² +) for softening hard water. |
| Thermal stability: When heated to high temperatures (>600°C) it decomposes to form sodium phosphate and oxygen. |
| Acid base: The aqueous solution is weakly basic and can react with acid to form phosphate. |
Preparation process of sodium hexametaphosphate
Sodium hexametaphosphorate produced by Riel Chemical is prepared from 85% thermal phosphoric acid and
99.0% high-quality caustic soda. After third-party test by SGS,
the finished product contains more than 68% phosphorus penoxide (see COA for details).
Sodium hexametaphosphate for use
1. Metal surface treatment
Cleaning agent: Used for metal surface cleaning and rust removal.
Rust inhibitor: prevents oxidation of the metal surface during metal processing.
2. Medicine and cosmetics
Stabilizers: In pharmaceuticals and cosmetics, sodium hexametaphosphate is used as a stabilizer to
prevent components from breaking down or settling.
Chelating agent: Used to remove heavy metal ions and improve product safety.
3. Agriculture
Fertilizer additive: Sodium hempetaphosphate can be used as a fertilizer dispersant to improve fertilizer efficiency.
Pesticide additives: In pesticide preparations, help the active ingredient to disperse evenly.
4. Research and laboratories
Analytical reagent: Sodium hexametaphosphate can be used in chemical analysis as a chelating agent or buffer.
Experimental additives: Used in materials science and chemistry research to prepare specific solutions or dispersion systems.
