Abstract The present invention relates to a process for hydrocyanating 3-pentenenitrile. The process can include feeding 3-pentenenitrile and HCN to a hydrocyanation reaction zone that includes a Lewis acid promoter, nickel, and a phosphorus-containing ligand. In various embodiments, the process can also include controlling water concentration within the hydrocyanation reaction zone sufficient to maintain a high activity of the ligand catalyst complex while recycling at least a portion of the ligand catalyst complex.
