Patent

CA 2239618

This invention relates to a process which comprises reacting one or more reactants in the presence of a metal-organopolyphosphite ligand complex catalyst to produce a reaction product fluid comprising one or more products, wherein said process is conducted at a free organopolyphosphite ligand concentration sufficient to prevent and/or lessen hydrolytic degradation of the organopolyphosphite ligand and deactivation of the metal-organopolyphosphite ligand complex catalyst.

Procédé consistant à faire réagir un ou plusieurs réactifs en présence d'un catalyseur constitué d'un complexe métal-ligand organopolyphosphite de façon à obtenir un fluide produit par réaction constitué d'un ou de plusieurs produits. Ce procédé s'effectue à une concentration suffisante de ligand organopolyphosphite libre pour empêcher et/ou limiter la dégradation hydrolytique du ligand organopolyphosphite et la désactivation du catalyseur constitué d'un complexe métal-ligand organopolyphosphite.
