Solutions of cobalt carbonyl and cobalt carbonyl hydride in organic solvents are prepared by treating aqueous solutions of cobalt salts with carbon monoxide and hydrogen at a temperature of from 50 DEG to 200 DEG C and a pressure of from 50 to 500 atmospheres in the presence of solvents which are sparingly water-miscible or are water-immiscible and which have a content of cobalt carbonyl, cobalt carbonyl hydride or mixtures thereof, the starting materials and the organic solvents being passed cocurrently through a zone in which a turbulent flow is maintained. The improvement includes using n-butanol as solvent. Solutions of cobalt carbonyl and cobalt carbonyl hydride in n-butanol are suitable as catalyst solutions for oxo syntheses. |
