Procedure

To a solution of 46.9 g of triphenylphosphine oxide (ca 70% strength) in 230 mL of chlorobenzene there were added, dropwise over a period of 10 minutes, 6.9 g of 98% strength sulfuric acid. The purification was carried out in a manner similar to that described in Example 1 and there were obtained 38.3 g of triphenylphosphine oxide/sulfuric acid adduct and, from this, 27.9 g of triphenylphosphine oxide (based on 70% starting product this points to a refind rate of 85%).
