35 g (0.1 mol) of 2.4-di-tert.-butylphenyl dibutylphosphinite from Example 5 were reacted in 100 ml of acetonitrile with 2.0 g (0.11 mol) of water at 20° C., and the mixture was then stirred at 70° C. for 1 hour. The solvent was distilled off in vacuo, 50 ml of water and 100 ml of ethyl acetate were added, the phases were separated, and the organic phase was extracted two more times with 50 ml each of water. The combined aqueous phases were evaporated, and the residue distilled in vacuo, giving 10.2 g (70%) of a colorless liquid having a boiling point of 102° to 104° C./0.25 mbar.
