Industrial Grade 58%~60% Sodium Acetate Ph 8~9 for Chemical Raw Materials

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)

Use of sodium acetate in chemical raw materials

1. Chemical synthesis
(1) Intermediates
Principle of action:

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

Application scenario:

Acetate synthesis: Used to synthesize ethyl acetate, butyl acetate and other solvents.

Acetic anhydride synthesis: Used to synthesize acetic anhydride as an acetylation reagent.

(2) Catalyst
Principle of action:

Sodium acetate can be used as catalyst or cocatalyst in some chemical reactions.

Application scenario:

Esterification reaction: Used to catalyze esterification reaction to improve reaction efficiency.

Polymerization reaction: Used to catalyze some polymerization reactions, such as the synthesis of polyvinyl alcohol.

2. Buffer
Principle of action:

Sodium acetate aqueous solution is weakly alkaline and can be used as a buffer to stabilize the pH value of the reaction system.

Application scenario:

Chemical reaction: used to stabilize the pH value of the chemical reaction and improve the selectivity and yield of the reaction.

Biochemistry: Used to formulate buffer solutions to stabilize the pH of biochemical reactions.

3. Complexing agent
Principle of action:

Sodium acetate can form complexes with certain metal ions and change its chemical properties.

Application scenario:

Metal ion stabilization: Used to stabilize metal ions and prevent their precipitation or oxidation.

Catalyst preparation: Used to prepare some metal catalysts, such as copper catalysts, nickel catalysts.

4. Electroplating industry
Principle of action:

Sodium acetate can be used as an additive in the plating solution to improve the quality and properties of the coating.

Application scenario:

Nickel plating: Adding sodium acetate to nickel plating solution can improve the brightness

and corrosion resistance of the coating.

Galvanizing: Adding sodium acetate to the galvanizing solution can improve the uniformity and adhesion of the coating.
