Key Properties
Adipic Acid is a dicarboxylic acid with the molecular formula C₆H₁₀O₄ and CAS No. 124-04-9. It appears as a white crystalline powder with a mild acidic character. It has a melting point of about 152 °C and low solubility in water, but is soluble in alcohol and acetone.
Key Features
Adipic Acid is an important industrial intermediate with good chemical stability and broad compatibility in polymer systems. It is mainly valued for its role in producing nylon 6,6, polyurethanes, plasticizers, and specialty chemical products. It can also be used as an acidulant in selected food applications.
Main Applications
Adipic Acid is primarily used as a key raw material for nylon 6,6 production. It is also used in polyurethanes, foams, plasticizers, lubricants, detergents, and food additives. In industrial systems, it supports the production of durable polymers, flexible materials, and performance additives.
Production Process
Adipic Acid is mainly produced by the oxidation of cyclohexanol and cyclohexanone mixture, also known as KA oil, using nitric acid. This process generates crude adipic acid, which is then purified through crystallization and drying to obtain industrial-grade or high-purity products.
