Abstract: A method for recovering a transition metal, e.g., rhodium, from a non-polar organic solution containing non-polar organic solvent-soluble and polar solvent-insoluble coordination complex of the transition metal and a non-polar organic solvent-soluble and polar solvent-insoluble ligand, e.g., an organophosphorus ligand, by contacting the non-polar organic solution with a polar solution of an ionic organophosphine ligand, the transition metal then can be transferred back into a non-polar solution for reuse. In one embodiment rhodium is rendered amenable for back-extraction by treating the polar solution with a suitable conditioning reagent.

Abstract: In this process for recovering noble metals of group VIII from a contaminated catalyst solution originating from the carbonylation of methyl acetate and/or dimethylether (the catalyst solution containing carbonyl complexes of these noble metals, organic or inorganic promoters, undistillable organic contaminants as well as volatiles) the volatiles are distillatively removed from the catalyst solution and the remaining distillation residue is water-treated, whereby the noble metal/carbonyl-complex is precipitated together with the organic contaminants and is separated from the aqueous phase, while the promotor is dissolved and recovered in conventional manner. The noble metals are then set free in elemental form by subjecting the noble metal/carbonyl-complex separated and contaminated with organic polymers at temperatures of 150.degree. to 300.degree. C. to treatment with an ethyleneglycoldialkylether solvent of the formula R(--OCH.sub.2 --CH.sub.2).sub.n --OR, in which n stands for a number of from 1 to 4 and R stands for identical or different alkyl groups having from 1 to 6 carbon atoms. The noble metal can then be recovered by filtration, and the solvent can be freed of organic contaminants by distillation.
