Hydroformylation using low volatile phosphine ligands

Abstract From the Canadian patent

An improved non-aqueous hydroformylation process for producing aldehydes which comprises reacting an olefinically unsaturated organic compound with carbon monoxide and hydrogen in a, non-aqueous hydroformylation reaction medium containing the olefinically unsaturated organic compound, aldehyde product, solubilized Group VIII transition metal-phosphorus ligand complex catalyst and solubilized free phosphorus ligand the, improvement comprising employing as the phosphorus ligand of said complex catalyst and as said free phosphorus ligand, a monosulfonated tertiary phosphine metal salt and wherein said, hydroformylation reaction medium also contains at lest a sufficient amount of an added …
