    Abstract: To separate and recover rhodium, the distillation residues of oxo synthesis products are initially treated with an oxidant. Then the reaction mixture is reacted, in the presence of carbon monoxide (or a compound which splits off carbon monoxide), with an aqueous solution of a reagent forming a water-soluble complex compound with rhodium. The reaction mixture breaks into an organic phase and an aqueous phase, the complex goes to the aqueous phase as it is substantially insoluble in the organic phase.
