Abstract: A method of purifying an organic diphosphite of general formula (I) The method comprises providing a crude organic diphosphite of general formula (I) that is at least partly dissolved in a first solvent (L1), wherein (L1) is selected from the group consisting of alkylbenzenes, aryl alkyl ethers, chlorobenzene, and mixtures thereof, and precipitating by admixing with a second solvent (L2) selected from the group consisting of linear C1-C4-alkanols, ethylene glycol di(C1-C4-alkyl) ethers, and mixtures thereof, and separating off the precipitated organic diphosphite from the solvents.
