ABSTRACT:
The present invention relates to a process for recovering the cobalt carbonyl catalyst used, in which a water-soluble cobalt salt is first prepared by addition of acid and this is subsequently precipitated as cobalt hydroxide. This cobalt hydroxide is then reacted with the N-acyl-.alpha.-amino acid derivative for whose preparation the cobalt carbonyl catalyst is intended, and the resulting cobalt-containing melt is converted into the cobalt carbonyl catalyst in the presence of a mixture of carbon monoxide and hydrogen.
