Abstract

A process for the preparation of aldehydes by hydroformylation of olefins in the presence of an aqueous solution containing rhodium as a catalyst. The aqueous solution preferably contains rhodium in a concentration of 450 to 800 weight-ppm and sulfonated or carboxylated triarylphosphines as complex ligands in a concentration of 25 to 30% by weight, both based on the aqueous solution.
