    Abstract: A process for separating rhodium from mixtures thereof, comprising extracting said rhodium with an aqueous solution of a rhodium complexing agent and a solubilizer. A process for preparing aldehydes in the presence of both the complexing agent and the solubilizer is also set forth. The solubilizer is generally selected from salts of carboxylic acids having 8-20 carbon atoms, alkyl sulfonates, alkyl aryl sulfonates, amines and quaternary ammonium compounds of Formula II ##STR1## wherein A is alkyl, alkoxy, hydroxyalkyl, aryl having 6-25 carbon atoms, or R.sup.7 CONHCH.sub.2 CH.sub.2 CH.sub.2 --wherein R.sup.7 is alkyl having 5-11 carbon atoms; B is an alkyl having 1-25 carbon atoms, an aryl having 6-25 carbon atoms, or an .omega.-hydroxy alkyl having 1-4 carbon atoms; C and D are each independently an alkyl or .omega.-hydroxy alkyl having 1-4 carbon atoms or form, together with each other and the bridging N, a 5 or 6 membered heterocyclic ring; E is a halide, sulfate, borate, sulfonate, lactate or citrate; and p is the number of charges on E. The rhodium complexing agent is preferably a triaryl phosphine carboxylate or sulfonate.

    Abstract: The present invention relates to a process for the preparation of aldehydes by the reaction of olefinic compounds with hydrogen and carbon monoxide in the presence of a catalyst system containing rhodium and aromatic phosphines. The aromatic phosphines are soluble in organic media and represent salts of sulfonated or carboxylated triarylphosphines which are insoluble in water. After hydroformylation, the reaction product is treated with a diluted aqueous solution of a base and the aqueous phase containing rhodium and aromatic phosphines is separated. Thus, thermal loading of the catalyst, for example by the redistillation of the reaction product, is avoided.
