Abstract:
Process for hydrocyanating a substrate selected from 2-, 3-, or 4-pentenenitrile and/or 2-methyl-3-butenenitrile or mixtures thereof by contacting the substrate with HCN in the presence of a zero-valent nickel catalyst and a promoter that is obtained as a byproduct of titanium ore chlorination.
