Global Market Recommended Sodium Acetate 58%~60% for Industrial Applications

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. Water treatment
pH regulator:

Sodium acetate solution is weakly alkaline and can be used to adjust the pH value of water.

As a buffer, sodium acetate can stabilize the pH value of the water and prevent acid-base fluctuations.

Carbon source supplement:

Sodium acetate can be used as a carbon source to promote the growth and metabolism of microorganisms.

In the biological treatment process, sodium acetate provides organic carbon

and enhances the activity of microorganisms.

Scale inhibitor:

Sodium acetate can form soluble complexes with calcium and magnesium ions in water to

prevent the formation of scale.

Heavy metal removal:

Sodium acetate can react with some heavy metal ions (such as lead, chromium) to precipitate,

which is used to remove heavy metals from wastewater.

2. Chemical synthesis
Intermediate:

Sodium acetate is used as an intermediate to synthesize other chemicals, such as acetate and acetic anhydride.

Catalyst:

In some chemical reactions, sodium acetate can be used as a catalyst or cocatalyst.

3. Textile industry
Dye fixing agent:

Sodium acetate is used in the dyeing process of textiles to help dyes better adhere to fibers

and improve dyeing fastness.

Neutralizer:

It is used to neutralize acidic wastewater and adjust pH value.

4. Electroplating industry
Plating solution additive:

Sodium acetate is used in electroplating solution to improve coating quality.

Buffer:

Used to stabilize the pH value of the plating solution and prevent acid-base fluctuations.
