Buy 58%~60% Sodium Acetate White Crystal for Printing And Dyeing Industry

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. Food industry
Food Additives (E262) :

Acidity regulator: Used to regulate the pH of food to improve taste and shelf life.

Preservatives: inhibit microbial growth and extend food shelf life.

Flavor enhancer: to enhance the flavor of food, often used in snacks, condiments and canned foods.

Buffer: stabilizes pH in food processing and prevents acid-base fluctuations.

2. Medicine and Biochemistry
Buffer:

Used in pharmaceutical and biological experiments to stabilize the pH of solutions.

It is commonly used in cell culture, protein purification and enzyme reactions.

Dialysate: Used as an electrolyte component in hemodialysis.

Drug synthesis: Used as an intermediate or reactant to synthesize certain drugs.

3. Industrial applications
Textile industry:

Dye fixing agent: Help dye better adhere to the fiber, improve the fastness of dyeing.

Neutralizer: Used to neutralize acidic wastewater.

Electroplating industry:

Electroplating solution additive: Adjust the pH value of electroplating solution to improve electroplating effect.

Concrete additives:

Antifreeze: reduce the freezing point of concrete, used in winter construction.

Retarder: delay the setting time of concrete and facilitate construction operation.

4. Heat 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.
