Improved hydroformylation process employing a catalyst based on cobalt and/or rhodium in a non-aqueous ionic solvent.

摘要

Hydroformylation reaction is effected in presence of non-aqueous ionic solvent comprising a salt with a quaternary ammonium and/or quaternary phosphonium and an anion, and a complex of cobalt and/or rhodium coordinated by a nitrogeneous or phosphorated ligand. Hydroformylation reaction is effected in presence of non-aqueous ionic solvent comprising a salt (Q+A-), in which Q+ is quaternary ammonium and/or quaternary phosphonium and A- is an anion, and a complex of cobalt and/or rhodium coordinated by a nitrogeneous or phosphorated ligand with an ionic function (Q<1>)+ or (A<1>)-, where Q<1> and A<1> are of the same chemical nature as Q+ and A-.
