Adiponitrile is made by reacting 3-pentenenitrile with hydrogen cyanide. The 3-pentenenitrile is made by reacting 1,3-butadiene with hydrogen cyanide and by isomerizing 2-methyl-3-butenenitrile. Phenolic compounds, such as phenol and cresols, are present as a catalyst impurity or as a catalyst degradation product. Phenolic compounds are removed during the nitrile manufacturing process.
