1. Food industry: Sodium acetate is used as a preservative and acidifier to help maintain a specific pH level in food processing, thus preventing the growth of harmful bacteria and improving the taste of food. It can also be used to regulate the pH of foods to provide specific flavors

2. Chemical manufacturing: Sodium acetate can be used in the manufacture of various chemical products such as furanacrylic acid, acetate and chloroacetic acid. It plays an important role in chemical production

3. Sewage treatment: Sodium acetate is widely used in sewage treatment, as a new material, it can be used as a treatment agent for sewage, effectively removing impurities in sewage, improving water quality, and reducing pollution of the water environment

4. Printing and dyeing industry: In the process of printing and dyeing, sodium acetate is used as a neutralizing agent to adjust the pH value, as well as to neutralize the acidity in dyeing, in order to ensure the uniform distribution of dyestuffs and the stability of color.

5. Organic synthesis: Sodium acetate is used as acetylation subsidizer in organic synthesis for synthesizing cinnamic acid, benzyl acetate and other compounds.

6. Detergents and cleaners: Sodium acetate can neutralize the large amount of acid discharged from factories, maintain the luster of metal surfaces, while removing rust and stains

7. Pharmaceutical and dyeing mordants: In the pharmaceutical and dyeing industries, sodium acetate is used as a mordant to help fix dyes on fabrics and in the preparation of buffers.

8. Environmental science: Sodium acetate is also used in the field of environmental science, such as the extraction of nucleic acids, by adding sodium acetate buffer to adjust the salt ion concentration, neutralize the negative charge of the nucleic acid molecules, to facilitate the subsequent separation and purification operations.
