C2H3NaO2 High Purity Sodium Acetate Ph 8.0-9.0 for Environmental Protection Field

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 environmental protection

1. Dechlorinator
Principle of action:

Sodium acetate can be used to remove residual chlorine in water and improve water quality.

Through a chemical reaction, the residual chlorine is converted into harmless chloride.

Application scenario:

Drinking water treatment: Remove residual chlorine in drinking water to improve water quality.

Industrial water treatment: Remove residual chlorine in industrial water to prevent equipment corrosion.

2. Snow melting agent
Principle of action:

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.

Application scenario:

Road deicing: used for winter road deicing to reduce the damage to the environment and vehicles.

Airport deicing: Used for deicing airport runways to ensure flight safety.

3. Soil remediation
Principle of action:

Sodium acetate can be used in soil remediation to promote microbial degradation of organic pollutants.

By providing a carbon source, it enhances the activity of microorganisms in the soil and accelerates the degradation of pollutants.

Application scenario:

Organic contaminated soil remediation: used to repair soil contaminated by organic matter such as oil and pesticides.

4. Other applications
(1) Waste gas treatment
Principle of action:

Sodium acetate can be used to absorb acidic gases (such as sulfur dioxide, hydrogen chloride) in exhaust gases.

Through a chemical reaction, acidic gas is converted into harmless salts.

Application scenario:

Industrial waste gas treatment: used to treat acidic waste gas emitted by chemical plants, power plants, etc.

(2) Environmentally friendly chemicals
Principle of action:

As an environmentally friendly chemical, sodium acetate can replace some toxic chemicals

and reduce environmental pollution.

Application scenario:

Green chemical process: Used for environmental protection chemical process to

meet the requirements of environmental protection regulations.
