Industrial Grade 58%~60% Sodium Acetate White Crystal for Sewage Treatment
Sodium acetate properties
1. Chemical properties
Chemical formula: CH₃COONa
Molecular weight: 82.03 g/mol (anhydrous matter); 136.08 g/mol (trihydrate)
Structure: Composed of the radical acetate ion (CH₃COO⁻) and sodium ion (Na +).
pH value: The aqueous solution is weakly alkaline, pH is about 8-9.
2. Physical properties
Appearance:
Anhydrous sodium acetate: white crystalline powder.
Sodium acetate trihydrate (CH₃COONa·3H₂O) : colorless transparent crystal.
Solubility:
Soluble in water, solubility increases significantly with temperature (at 20°C, about 46.5 g per 100 mL of water).
Slightly soluble in ethanol, insoluble.
Melting point:
Anhydrous sodium acetate: 324°C.
Sodium acetate trihydrate: 58°C (dehydration decomposition).
Density:
Anhydrous sodium acetate: 1.528 g/cm³.
Sodium acetate trihydrate: 1.45g /cm³.
Hygroscopic: Sodium acetate trihydrate is easy to hygroscopic, and anhydrous sodium acetate hygroscopic is low.
3. Thermal stability
Heated decomposition. When heated to high temperatures, sodium acetate decomposes to
form sodium carbonate (Na₂CO₃) and methane (CH₄)
Sodium acetate application
1. Environmental protection and wastewater treatment
Wastewater treatment:
It is used to neutralize acidic wastewater and adjust pH value.
As a carbon source, it promotes microbial degradation of organic pollutants.
Denitrification agent: In sewage treatment, as the carbon source of denitrification process.
2. Laboratory and scientific research
Buffer solution: Used to prepare pH buffer solution, widely used in chemical and biological experiments.
Reagent: Used as a reagent or catalyst for chemical reactions.
Standard solution: Used to calibrate an instrument or as a standard substance.
3. Other applications
Snow melting agent: As an environmentally friendly snow melting agent, it is used for deicing roads and airports.
Feed additive: Used in animal feed to regulate the pH of the digestive system.
Photographic industry: as one of the components of the developer.
4. Advantages of sodium acetate
Versatility: It is widely used in food, medicine, industry and other fields.
Environmental protection: low toxicity and easy degradation, friendly to the environment.
Cost effective: Low price, easy to mass production.
