The subject of the present invention is a process for bleaching a product obtained by a homogeneous catalytic reaction in which the catalyst used is a metal chosen from the group comprising: palladium, cobalt, platinum, nickel and their mixtures, said product comprising as a result, colored metal agglomerates. This process consists essentially of (1) oxidizing the metal (s) M constituting the agglomerates, and (2) trapping the oxidized metal forms (Mox) thus obtained using at least one ligand L doublet carrier (s) free electron (s), selected from phosphorus compounds, and / or from nitrogen compounds, and / or from sulfur compounds. |
