Trace amounts of catalysts which are present in products resulting from organic reactions, such as rhodium which is present in the alcohol products resulting from a hydroformylation reaction, may be removed by treating the aforesaid products with a solid adsorbent such as a metal compound of Groups IA or IIA of the Periodic Table, molecular sieves or ion-exchange resins at a temperature in the range of from about ambient to about 100.degree. C. and a pressure in the range of from about atmospheric to about 100 atmospheres.
