1. Adipic acid is mainly used as a raw material for nylon 66 and engineering plastics, and is also used for the production of various ester products, as a raw material for polyurethane elastomers, and as an acidulant for various foods and beverages. Sometimes outperforms citric and tartaric acids.
2. Adipic acid is also a raw material for medicine, yeast purification, pesticides, adhesives, synthetic leather, synthetic dyes and fragrances.
3. Adipic acid has a soft and long-lasting sour taste, and the pH value changes less in a large concentration range, so it is a better pH value regulator.
