Acids; acyclic polycarboxylic acids; adipic acid, its salts and esters

HS v2017 Code: 291712

About acids; acyclic polycarboxylic acids; adipic acid, its salts and esters

HS code 291712 covers the production and trade of adipic acid, a critical chemical compound used in the manufacturing of various products. Adipic acid is an important acyclic polycarboxylic acid that finds widespread application in the plastics, textiles, and pharmaceutical industries. As a key input for the production of nylon, adipic acid plays a vital role in the global textile and apparel supply chain. Its versatility and high demand make it an essential component of the broader chemical industry and the international trade landscape.

Production process

Adipic acid is primarily produced through the oxidation of cyclohexanol or cyclohexanone, which are derived from the hydrogenation of benzene. The process involves several steps, including the initial oxidation, purification, and final crystallization to obtain the desired adipic acid product. Manufacturers utilize a range of catalysts and reaction conditions to optimize the yield and purity of the final output.

Production inputs

The production of adipic acid requires several key inputs, including benzene, hydrogen, and various catalysts and reagents. Specialized equipment, such as reactors, distillation columns, and crystallization units, are also essential for the manufacturing process. Additionally, the industry relies on a robust supply chain of raw materials, energy sources, and transportation infrastructure to support the global trade of adipic acid and its derivatives.

Production outputs

Adipic acid is a versatile chemical that serves as a precursor for the production of various downstream products. Its primary application is in the manufacture of nylon 54 Manmade filaments, a widely used synthetic fiber in the textile and apparel industries. Adipic acid is also used in the production of polyurethanes, plasticizers, and other specialty chemicals. The outputs of this industry are often consumed by 39 Plastics and articles thereof, 29 Organic chemicals, and 55 Textile articles.
