Acrylonitrile is a colorless, flammable liquid. Its vapors may explode when exposed to an open flame. Acrylonitrile does not occur naturally. It is produced in very large amounts by several chemical industries in the United States and its requirement and demand has increased in recent years. The largest users of acrylonitrile are chemical industries that make acrylic and modacrylic fibers, high impact acrylonitrile-butadiene-styrene (ABS) plastics. Acrylonitrile is also used in business machines, luggage, and construction material, in the manufacturing of styrene-acrylonitrile (SAN) plastics for automotive and household goods, and in packaging material. Adiponitrile is used to make nylon, dyes, drugs, and pesticides.

Heterogeneous catalytic hydrogenation reactions of aliphatic dinitriles are of importance for industrial diamines production. 1,6-Diaminohexane (hexamethylenediamine, HMDA) is mainly used in nylon 66 manufacture and up to 2 MT is produced yearly. Heterogeneous catalytic hydrogenation of adiponitrile is by far the most used industrial route to produce this aliphatic diamine [1].

Cyanide is also required for some chemical syntheses, such as cyanation reactions. A well-known example is the DuPont process to adiponitrile, the precursor of polyamide 6.6. In this process, adiponitrile is obtained by the Ni-catalyzed hydrocyanation of 1,3-butadiene, and the resulting adiponitrile is reduced to hexamethylene diamine, one of the polyamide monomers (Bini et al., 2010).
