ABSTRACT:
A process for the separation of rhodium catalysts from high-boiling and tarry distillation residues obtained in the processing of reaction products from organic, catalytic reactions, utilizing dissolved, homogenous rhodium complex catalysts, such as hydroformylation reactions, hydrocarboxylation reactions, isomerization, dimerization and oligomerization reactions, by passing a stream of a non-oxidizing, and preferably reducing, carrier gas, such as hydrogen or a hydrogen-containing gas, through the residue at an elevated temperature to selectively remove the organic constituents, leaving a heterogenous residue containing the rhodium, and dissolving this heterogenous residue in an inorganic acid to thereby form a water-soluble rhodium compound, which is suitable for the production of a complex rhodium catalyst in the known manner. Oleum is preferably used as the inorganic acid, and after mixing with the heterogenous residue, a portion is preferably fumed off.
