Procedure

To 200 g (0.531 mol) of the triphenylphosphine oxide/sulfuric acid adduct in 1500 mL of chlorobenzene there were stirred in 1500 mL of water over a period of one hour. Following phase separation, the aqueous phase was extracted three times with 500 mL of chlorobenzene each time. Following the removal of the solvent there were obtained 146 g (97.5%) of triphenylphosphine oxide.
