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.

Process for making nitriles

A method of improving flowability of adipic acid includes adding to the adipic acid at a relatively low temperature a flowability improving agent, such as an acyclic saturated monobasic acid containing 10 to 22 carbon atoms or an acyclic saturated dibasic acid containing 10 to 14 carbon atoms.
