Industrial Grade High Quality Sodium Acetate for Chemical Raw Materials

Key properties of sodium acetate

1. Basic information
Chemical formula: CH₃COONa·3H₂O

CAS Number: 6131-90-4

Molecular weight: 136.08 g/mol

Appearance: Colorless transparent crystals or white crystalline powder

Smell: Odorless or slightly acetic acid smell

pH value (1% aqueous solution) : ~8.0 (weakly alkaline)

2. Physical and chemical properties
Attribute value/description
Melting point: 58℃ (Dehydration decomposition, loss of crystalline water)
Density: 1.45 g/cm³ (20℃)
Solubility: Readily soluble in water (76 g/100 mL, 20℃), slightly soluble in ethanol
Strong hygroscopicity (should be stored in a sealed container)
It is stable at room temperature. When heated above 120℃, it dehydrates to form anhydrous sodium acetate
3. Main Uses
Buffer: Regulates pH, used in biochemical experiments, electroplating solutions, and pharmaceuticals.

Hot bag raw materials: Supersaturated solution crystallization releases heat (hand warmers, medical hot compresses).

Food additives (E262i) : Preservatives, acidity regulators (food grade required).

Industrial uses: dyeing and printing mordant, rubber coagulant, sewage treatment.

4. Security and Storage
Toxicity: Low toxicity (Oral administration in LD₅₀ rats: 3530 mg/kg), but high concentrations may irritate the eyes/skin.

Protection: Wear gloves/goggles during operation to avoid inhaling dust.

Storage: Keep sealed to prevent moisture and store in a cool and dry place (avoid storage with strong acids and oxidants).

5. Precautions
Heating risk: The dehydration process may cause caking, and decomposition at high temperatures (>400℃) may produce flammable gas.

Solution treatment: The discharge of wastewater containing sodium acetate must comply with environmental protection standards (high concentration may affect the water body ecology).

If technical parameters (such as spectral data and thermodynamic properties) are required, further detection standards (such as ACS and USP grades) can be provided.

In which industries is sodium acetate trihydrate applied

1. Chemical industry
Buffer and pH regulator

It is used for electroplating solutions and metal surface treatment to maintain a stable pH value of the solution.

It is used as a neutralizing agent in the production of dyes and pigments to adjust the pH of the reaction system.

Organic synthesis intermediate

It participates in reactions such as esterification and acetylation, for example, in the synthesis of cellulose acetate and pharmaceutical intermediates.

2. Food industry (Food grade E262i required)
Acidity regulators and preservatives

It is used in condiments (such as potato chips, sauces), bread, etc., to inhibit the growth of microorganisms and regulate the sourness.

Food preservation

It is used as a mild preservative in meat processing to extend the shelf life.

3. Medical care and daily chemicals
Heat therapy products

Supersaturated solutions are used in disposable hand warmers and medical heat packs (based on the principle of crystallization and heat release).

Pharmaceutical excipients

As a drug buffer or osmotic pressure regulator (such as injection solutions, eye drops).

4. Environmental Protection and Sewage Treatment
Carbon source supplement

It is used as a denitrifying carbon source in sewage treatment to promote microbial denitrification (especially suitable for low-temperature wastewater).

Heavy metal precipitating agent

Assist in precipitating heavy metal ions (such as lead and copper) in industrial wastewater.

5. Textile and Dyeing
Mordant

Fix the dye in the dyeing process to enhance the color fastness of the fabric.

Neutralizing agent

Remove residual acids (such as sulfuric acid) to prevent fiber damage.

6. Laboratory and Scientific Research
Biochemical buffer solution

Prepare buffer systems such as PBS for cell culture and DNA extraction.

Chemical reagent

As a standard substance or reaction substrate (such as in experiments to lower the freezing point).

7. Other special uses
De-icing agent

Environmentally friendly snow-melting components (less corrosive to concrete and plants than sodium chloride).

Rubber industry

As a latex coagulant, it accelerates the molding of rubber.
