How to recover rhodium |
| abstract |
A process for recovering rhodium from an organic reaction mixture comprising a rhodium / phosphite ligand complex, a phosphite decomposition product and a high boiling organic compound, comprising: A) subjecting the organic reaction mixture to an aqueous oxidation and / or acid treatment. C) a solution of a lipophilic phosphine and / or a lipophilic phosphite in a non-polar solvent, wherein the aqueous phase is removed and B) the aqueous phase is removed and C) is immiscible with the polar organic phase. Is added to the organic phase to form a two-phase mixture comprising a non-polar organic phase rich in rhodium and lipophilic phosphine and / or lipophilic phosphite and a polar organic phase rich in phosphite decomposition products and high boiling organic compounds. Or the polar organic phase is extracted by an immiscible non-polar organic solvent, resulting in a non-polar organic phase enriched in phosphite decomposition products and a rhodium-rich polar phase It resulted in two-phase mixture comprising a machine phase, D) method where the non-polar organic phase is separated from the polar organic phase. |
