PROCESS FOR THE PREPARATION OF A NICKEL/PHOSPHORUS LIGAND CATALYST FOR OLEFIN HYDROCYANATION

摘要

A process for preparing a hydrocyanation catalyst comprising contacting a bidentate phosphorous-containing ligand with a molar excess of nickel chloride in the presence of a nitrile solvent and a reducing metal which is more electropositive than nickel. Preferably, the nickel chloride is dried before use.
