CARBONYLATION PROCESS AND LIGAND COMPOSITION COMPRISING A BIDENTATE PHOSPHITE LIGAND AND A TERTIARY PHOSPHINE ANTI-OXIDANT

摘要

Disclosed is a carbonylation process comprising subjecting at least one olefin to hydroformylation in presence of a syngas, comprising carbon monoxide and hydrogen, at least one Group VIII transition metal catalyst or catalyst precursor and at least one phosphite ligand of Formula (I) and at least one anti-oxidant selected from the group consisting of tertiary phosphines, such as triarylphosphines, dicycloalkylarylphosphines and/or cycloalkyldiarylphosphines. In a further aspect the present invention refers to a ligand mixture comprising at least one phosphite ligand of Formula (I) and at least one said anti-oxidant.
