Versuchsvorschrift
A 0.5N aqueous sodium hydroxide solution was added to the oil phase obtained in Example 14, and, after 30 minutes stirring, air was blown thereinto at 70° C. for 2 hours. Then, the oil phase and the aqueous phase containing the precipitate were separated, and the aqueous phase was dried under reduced pressure to obtain 5.5 kg of 2-methylanthraquinone.
