ABSTRACT:
Noble metal or other preformer catalysts used to convert cobalt salts to hydrido cobalt carbonyl for use in the oxonation of olefins are reactivated or regenerated by treatment with a mixture of an aqueous organic acid solution and an alcohol at a temperature of about 120.degree. C. to 170.degree. C. and a pressure of about 13.78 MPa to 31.00 MPa for about 2 to 50 hours.
