58%~60% Laboratory Grade Sodium Acetate High Purity Suitable for Research Analysis
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)
The role of sodium acetate in industry
1. Snow melting agent
Environmentally friendly snow melting agent:
Sodium acetate is used as an environmentally friendly snow melting agent for deicing roads and airports.
Sodium acetate is less corrosive to the environment and equipment than traditional snow melting agents.
2. Hot pack
Hot pack:
Take advantage of the supercooled nature of sodium acetate trihydrate (CH₃ ·3H₂O) to make a reusable hot pack.
Through the principle of crystallization exothermic, continuous heat is provided for medical treatment or daily warmth.
3. Other applications
Concrete additives:
Sodium acetate is used in concrete as an antifreeze and retarder.
Flame retardant:
Sodium acetate is used to make flame retardant materials.
Optical materials:
Sodium acetate is used in the manufacture of optical glasses and crystals.
4. Use precautions
Dosage control:
According to the specific application requirements,
the amount of sodium acetate should be controlled reasonably to avoid excessive use.
Safety protection:
Sodium acetate is less toxic to humans, but it is still necessary to wear protective gear
and avoid direct contact with skin and eyes.
Environmental impact:
Sodium acetate is environmentally friendly, but it still needs to be used rationally to avoid excessive emissions.
