SGS Bulk Sodium Acetate White Crystal For Printing And Dyeing Industry

SGS 58%~60% Sodium Acetate White Crystal For Printing And Dyeing Industry

• 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

• Appearance: Anhydrous sodium acetate: white crystalline powder. Sodium acetate trihydrate: 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

Heated decomposition. When heated to high temperatures, sodium acetate decomposes to form sodium carbonate (Na₂CO₃) and methane (CH₄)

• Food Additives (E262): Acidity regulator to improve taste and shelf life
• Preservatives: inhibit microbial growth and extend food shelf life
• Flavor enhancer: enhances the flavor of food, often used in snacks, condiments and canned foods
• Buffer: stabilizes pH in food processing and prevents acid-base fluctuations

• Buffer: Used in pharmaceutical and biological experiments to stabilize pH
• Dialysate: Used as an electrolyte component in hemodialysis
• Drug synthesis: Used as an intermediate or reactant to synthesize certain drugs

• Textile industry: Dye fixing agent and neutralizer for acidic wastewater
• Electroplating industry: Adjusts pH value of electroplating solution
• Concrete additives: Antifreeze for winter construction and retarder for setting time

Utilizes the supercooled nature of sodium acetate trihydrate to make reusable hot packs through crystallization exothermic principle.
