Adipic acid, also known as hexanedioic acid (CAS 124-04-9), is a fundamental organic compound with a wide array of industrial applications. As a leading manufacturer and supplier of chemicals in China, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality adipic acid to meet global demand. This article aims to provide an overview of adipic acid's key properties, its primary production methods, and its vital position within the international chemical market.

Chemically, adipic acid is a white crystalline powder characterized by its dicarboxylic acid structure: HOOC(CH2)4COOH. This structure imparts crucial chemical reactivity, allowing it to undergo salt formation, esterification, and amidation reactions. These properties make it an indispensable intermediate for forming high molecular weight polymers through condensation reactions with diamines or diols. Its physical properties, such as its melting point and solubility, are critical for various industrial processes and formulations. For example, its role as a precursor for Nylon 66 is paramount, consuming approximately 60% of its global production.

The industrial synthesis of adipic acid predominantly involves the oxidation of a mixture of cyclohexanone and cyclohexanol (known as KA oil) using nitric acid. This process, while effective, is associated with the production of nitrous oxide (N2O), a potent greenhouse gas. Consequently, significant advancements have been made in implementing catalytic abatement technologies to convert N2O into nitrogen and oxygen, aligning production with environmental sustainability goals. Alternative production methods, such as the carbonylation of butadiene, are also explored to offer greener pathways.

The global market for adipic acid is substantial, driven by the continuous demand from sectors like automotive, textiles, construction, and healthcare. Its use as a monomer in polyamides (nylons), a component in plasticizers for PVC, a building block for polyurethanes, and an additive in lubricants, food, and pharmaceuticals underscores its versatility. As a manufacturer based in China, we are strategically positioned to serve this global market, offering reliable supply chains, competitive adipic acid pricing, and consistent product quality to international buyers.
