실험 절차
30 g of 5,5-dichloro-3,3-dimethylpentanoic acid and 18 g of NaOH, dissolved in 20 ml of water, are metered simultaneously into 60 ml of water while the pH is monitored, the metering being carried out at a rate such that the pH is 9-10 during the reaction. As soon as the pH value remains constant, the reaction is complete. The reaction mixture is brought to pH 3 with hydrochloric acid, and is extracted with dichloromethane. 20.9 g of 4-chloro-3,3-dimethyl-5-oxo-pentanoic acid of boiling point 110°-115° C./0.09 are obtained.
