Adipic Acid (chemical formula: C₆H₁₀O₄) is a dicarboxylic acid used primarily in the production of nylon and other industrial chemicals. It is a white crystalline solid with a slight, sweet odor. Adipic acid is highly soluble in water and alcohols and has a melting point of 151°C.
Key Uses:
- Nylon Production: The largest use of adipic acid is in the synthesis of nylon-6,6, a strong synthetic polymer used in textiles, automotive parts, and industrial applications.
- Plasticizers: It is used in the production of plasticizers, particularly in PVC and other flexible plastics.
- Food Additive: It is used as an acidulant in food and beverages, providing a slightly tart taste.
- Polyurethanes: It is a precursor for polyurethanes, which are used in foams, adhesives, et revêtements.
Environmental and Health Aspects:
While relatively non-toxic, adipic acid production generates nitrous oxide (N₂O), a potent greenhouse gas. Proper handling is essential to avoid respiratory or eye irritation.
