実験手順

A mixture of 3.4 g. (0.035 mole) of mesityl oxide and 1.0 g. of Amberlyst 15® sulfonic acid type ion-exchange resin was stirred at 25°-30° C., while 7.6 g. (0.050 mole) of 80% cumene hydroperoxide was added slowly. After stirring for 5 hours, the ion-exchange resin was separated by filtration, 25 ml. of pentane added and the filtrate washed with cold aqueous sodium bisulfite solution, sodium hydroxide solution and water. The pentane solution of the product was dried over anhydrous magnesium sulfate and the pentane removed under reduced pressure. The product recovered weighed 5.9 g. and was identified by its infrared spectrum.
