• General Description: 1,4-Dicyanobutane, also known as adiponitrile, is a key intermediate in the production of nylon 6,6 and can be synthesized through various methods, including catalytic ammoxidation of cyclohexanol or cyclohexanone, electrochemical conversion of glutamic acid, and nickel-catalyzed hydrocyanation of 3-pentenenitrile. These approaches highlight its industrial significance and the ongoing development of sustainable and efficient synthetic routes.
