Abstract: The present disclosure relates to methods of purifying organic diphosphites of the general formula (l) (See Formula I) wherein a crude organic diphosphite of the general formula (l) which is at least partly dissolved in a first solvent (L1) selected from among the group consisting of alkylbenzenes, aryl alkyl ethers, chlorobenzene and mixtures thereof is precipitated by admixing with a second solvent (L2) selected from among the group consisting of linear C1-C4-alkanols, ethylene glycol di(C1-C4-alkyl) ethers and mixtures thereof. Also provided are uses a transition metal catalyst comprising at least one organic diphosphite (l) obtained by the aforementioned purification method as ligand for hydroformylation, hydrocyanation or hydrogenation.
