Abstract: A process of hydrolyzing a monodentate, bidentate or tridentate phosphorus-based phosphite ester ligand or ligand blend for a transition metal catalyst comprising contacting the ligand or ligand blend with a hydrolysis catalyst of the formula (R 11 X 11 ) n P (OH) 3-n where n is 0, 1 or 2 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-X 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 ) Ρ-Χ 14 -Y-X 32 -P(X 34 -R 34 )-(X 33 -Y 2 -Κ 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 an optionally substituted C6-C20 arylene, followed by separation of the ligand hydrolysis products.
