Export Grade Sodium Acetate High Purity White Crystal Suitable for Textile 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)
What role does sodium acetate play in the textile industry
1. Dye fixing agent
Principle of action:
Sodium acetate acts as a mordant to help the dye adhere better to the fiber and improve the dyeing fastness.
By forming complex with dye molecules, the binding force of dye and fiber is enhanced.
Application scenario:
Cotton,silk and other natural fibers: improve dyeing uniformity and color brightness.
Synthetic fibers: Improve dye permeability and color retention.
2. pH regulator
Principle of action:
The sodium acetate solution is weakly alkaline and can be used to adjust the pH value of the dye solution.
As a buffer, sodium acetate can stabilize the pH value of the dye solution and prevent acid-base fluctuations.
Application scenario:
Dyeing process: Adjust the pH value of the dyeing solution to ensure the dyeing effect.
Post-treatment: neutralize acidic wastewater and adjust pH value.
3. Neutralizer
Principle of action:
Sodium acetate is used to neutralize acidic wastewater and regulate pH.
Application scenario:
Wastewater treatment: neutralize acidic wastewater in textile industry to meet discharge standards.
4. Other applications
Softener:
Sodium acetate is used in the finishing process of textiles to improve the softness of fabrics.
Flame retardant:
Sodium acetate is used in the manufacture of flame retardant textiles to improve the flame retardant properties of fabrics.
