Metal-ligand complex catalyzed processes

摘要

This invention relates to a method of stabilizing a metal-organopolyphosphite ligand complex catalyst against deactivation in a process which comprises reacting one or more reactants in the presence of a metal-organopolyphosphite ligand complex catalyst and optionally free organopolyphosphite ligand to produce a reaction product fluid comprising one or more products, which method comprises conducting said process in the presence of one or more free heterocyclic nitrogen compounds sufficient to prevent and/or lessen deactivation of the metal-organopolyphosphite ligand complex catalyst.
