Adiponitrile serves as a crucial intermediate in the production of nylon 6,6, a widely used synthetic polymer. It is primarily converted into hexamethylenediamine, which is then reacted with adipic acid to form the polymer. This application is significant in the textile, automotive, and electronics industries, where nylon 6,6 is valued for its strength, durability, and resistance to heat and chemicals. Additionally, adiponitrile is used in the synthesis of other specialty chemicals, including corrosion inhibitors and plasticizers, further extending its industrial relevance. Its role in enabling the production of high-performance materials underscores its importance in modern manufacturing processes.
