Applications
Sodium acetate 3AQ is applied in various ways, for instance:
1. Food Industry
Sodium acetate (as food additive E262) is used as a preservative and acidity regulator. It extends the shelf life of foods and is often used in ready meals, pickles, sauces and potato chips.
2. Pharmaceutical & Medical Applications
In pharmacy, it is used as a buffer solution and excipient in injectable solutions, infusions and tablets. It helps at stabilizing pH levels.
3. Water Treatment
Functions as a carbon source in biological denitrification processes in sewage treatment.
4. Textile Industry
Used for pH regulation during dyeing and pickling processes, especially in cotton processing.
5. Chemical Industrial & Laboratories
Used as a buffer at chemical reactions, especially in analytical and organic chemistry. Also used as a reagent in synthetic processes.
6. Heat Storage
Sodium acetate trihydrate is used in heat pads because of its ability to store and release heat during crystallization.
