Manufacturing process of Sodium Acetate
1. Reaction (Neutralization Process)
Acetic acid is taken in a reaction vessel, and sodium carbonate or sodium hydroxide is gradually added under controlled stirring.
The temperature is maintained between 50°C to 70°C to ensure complete neutralization.
The process continues until a clear sodium acetate solution is formed.
2. Filtration (Impurity Removal)
The sodium acetate solution is passed through a vacuum filter or centrifuge to remove insoluble impurities.
3. Evaporation (Concentration Process)
The filtered solution is heated in an evaporator at 80°C to 90°C under reduced pressure.
This step removes excess water, resulting in a highly concentrated sodium acetate solution.
4. Crystallization (Formation of Sodium Acetate Trihydrate)
The concentrated solution is cooled to 10°C to 20°C, leading to the crystallization of Sodium Acetate Trihydrate.
The crystals are collected using a centrifuge or vacuum filtration.
5. Dehydration (Conversion to Anhydrous Form)
The Sodium Acetate Trihydrate crystals are transferred to a drying oven or fluid bed dryer.
Heated at 120°C to 150°C under vacuum or dry air circulation to remove water molecules.
This results in the formation of Sodium Acetate Anhydrous.
6. Grinding & Sieving
The dried Sodium Acetate Anhydrous is milled and passed through a vibro sifter to achieve the desired particle size.
7. Final Packaging & Storage
The final Sodium Acetate Anhydrous powder is packed in moisture-proof HDPE bags or drums.
Stored in a cool, dry place to prevent moisture absorption.
