Verbessertes Hydroformylierungsverfahren mit Katalysatoren auf der Basis von Kobalt und/oder Rhodium in einem biphasischen Medium

摘要

The process is new. Process of liquid phase hydroformylation of olefinically unsaturated compounds is conducted in presence of at least one cobalt and/or rhodium complex coordinated by at least nitrogen ligand, and at least one ionic non-aqueous solvent comprising at least one organic/inorganic salt of formula Q<+>A<->: Q<+> = quaternary ammonium and/or quaternary phosphonium; A<-> = anion
