ABSTRACT:
The present invention relates to a hydroformylation method by conversion of olefins or olefinically unsaturated compounds in the presence of at least one rhodium compound and in the presence of sulfonated arylphosphines in ionic liquids, which are based on a quaternary singly-charged ammonium ion or the equivalent of a multiply charged ammonium ion and organic sulfonates or sulfates.
