HYDROFORMILIERUNG MIT LEICHT-FLUECHTIGEN PHOSPHINLIGANDEN.

摘要

A 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 of the general formula wherein R represents a radical containing 1 to 30 carbon atoms selected from alkyl, alkaryl, aralkyl and cycloalkyl radicals; M represents an alkali metal or alkaline earth metal cation; and n is 1 or 2 corresponding to the valence of the metal cation.
