For professionals in the chemical manufacturing and R&D sectors, a thorough understanding of key chemical intermediates is essential. Adipic Acid, identified by CAS number 124-04-9 and also known as hexanedioic acid, is a vital dicarboxylic acid with a white crystalline powder appearance. Its chemical formula, C6H10O4, points to its structure as a linear six-carbon chain with carboxyl groups at each end. This structure endows it with properties crucial for a wide range of industrial syntheses.

Physically, Adipic Acid is typically supplied as a white crystalline powder or granules, virtually odorless. Its melting point is around 152-154°C, indicating its solid state at ambient temperatures. Chemically, it is a diprotic acid, meaning it can donate two protons. Its pKa values are approximately 4.43 and 5.41, demonstrating its acidic nature. One of its advantageous properties is that it is practically non-hygroscopic, meaning it does not readily absorb moisture from the atmosphere, which simplifies handling and storage compared to some other organic acids.

The industrial significance of Adipic Acid is immense. By far, its largest application is as a monomer in the production of Nylon 66. This synthetic polyamide is formed through the polycondensation reaction of adipic acid with hexamethylene diamine. Nylon 66 is prized for its high tensile strength, stiffness, wear resistance, and thermal stability, making it a material of choice for textiles, automotive parts, electrical connectors, and many other engineering applications. When you buy Adipic Acid for this purpose, ensuring a high purity grade (e.g., 99% or higher) is critical for achieving the desired polymer properties.

Beyond Nylon 66, Adipic Acid is a key component in the synthesis of polyurethanes, contributing to the production of foams, elastomers, coatings, and adhesives that are used across numerous industries. Its esters also serve as plasticizers, particularly for PVC, enhancing material flexibility. In addition to these major polymer applications, Adipic Acid finds uses as a food acidulant, a component in lubricants, and in the synthesis of various other organic chemicals. For professionals seeking to purchase Adipic Acid, understanding these applications helps in specifying the required grade and quantity.
