China and the United States are the leading exporters of adipic acid, collectively accounting for a majority of global shipments, while Germany, South Korea, and Mexico are the largest importers, driven by downstream nylon-6,6 and polyurethane production. Exports from China have remained stable over the past three years, while U.S. exports increased modestly amid steady demand in North America and Europe; adipic acid prices have trended upward since mid-2023, reflecting tighter supply margins and feedstock cost pressures.
Adipic acid is a white, crystalline solid with a faint, characteristic odor and low volatility; it has a melting point of approximately 152 °C and is sparingly soluble in water. It is a saturated aliphatic dicarboxylic acid and serves primarily as a key chemical intermediate. Its principal industrial use is in the production of nylon 6,6 polyamide via condensation polymerization with hexamethylenediamine. It is also employed in the synthesis of polyurethane foams, plasticizers (e.g., for PVC), and food additives (as an acidulant). Typical application areas include polymers, coatings, adhesives, and synthetic fibers.
Raw material for pharmaceuticals, perfume fixative.
Adipic acid is the organic compound with the formula (CH2)4(COOH)2. From the industrial perspective, it is the most important dicarboxylic acid: About 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon. Adipic acid otherwise rarely occurs in nature.
