Abstract: A method of stabilizing a phosphorus-based ligand or a ligand blend comprising a plurality of phosphorus-based ligands, wherein the ligand or ligand blend comprises one or more of (i) a bidentate biphosphite ligand of formula (III), (R 12 -X 12 ) (R 13 -X 13 )P-X 14 -Y-Χ 24 -P (X 22 -R 22 ) (X 23 -R 23 ) (ii) a tridentate triphosphite ligand of formula (IIIΑ) (R 12 -X 12 ) (R 13 -X 13 )P-X 14 -Y-Χ 32 -P(X 34 -R 34 )-(X 33 -Y 2 -R 24 -P(X 23 -R 23 )-(X 22 -R 22 ) or (iii) a monodentate phosphite ligand of formula (IV) P(X 1 -R 1 )(X 2 -R 2 )(X 3 -R 3 ) where each X is oxygen or a bond and each Y is optionally substituted C6-C20 arylene; the process comprising forming a mixture of the ligand or the ligand blend with a liquid which partially or fully solubilizes the ligand or ligand blend, the liquid consisting essentially of one or more of: (a) a solvent system that does not contain peroxidizable species; or, (b) a solvent system that is substantially free of a dissolved metal.
