Title:
PROCESS FOR THE PREPARATION OF A NICKEL/PHOSPHORUS LIGAND CATALYST FOR OLEFIN HYDROCYANATION
Document Type and Number:
WIPO Patent Application WO2003045555
Kind Code:
A3
Abstract:
A process for preparing a hydrocyanation catalyst comprising contacting a bidentate phosphorous-containing ligand with a 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.
