| titleOfInvention | Process for the recovery of cobalt carbonyl catalysts used in the production of N-acyl-alpha-amino acid derivatives by amidocarbonylation |
| abstract | The present invention relates to a process for recovering cobalt carbonyl catalysts used to produce N-acyl-apha-aminoacid derivatives by amidocarbonylation, comprising the following steps: addition of an aqueous hydrogen peroxide solution to the reaction solution obtained after production of the N-acyl- alpha -aminoacid derivative; followed by separation of the aqueous phase containing water-soluble cobalt salt (II) from the phase containing the non-aqueous product; addition of the alkali metal salt of the N-acyl-alpha-aminoacid derivative to the aqueous phase of the previous step of the process; subsequent separation of the precipitate obtained from the N-acyl-alpha-amino acid derivative alkali metal salt, and finally, transformation of the N-acyl-alpha-amino acid derivativealkali metal salt thus obtained in the presence of a mixture of carbon and hydrogen monoxide in a cobalt carbonyl catalyst. |
