참여 물질

반응 단계

A reaction mixture of 62.2 g. (0.45 mole) of isophorone, 104 g. (0.9 mole) of 78% t-butyl hydroperoxide and 32.4 g. of Amberlyst 15® sulfonic acid type ion-exchange resin was stirred at 40° C. for 48 hours and at 50° C. for one hour. The ion-exchange resin was separated by filtration, the filtrate diluted with pentane and the pentane solution washed with water and sodium bisulfite solution. After drying over anhydrous magnesium sulfate, the pentane was removed under reduced pressure. The recovered product weighed 74.7 g. (72.8% of the calculated amount). The infrared spectrum had a strong absorption band in the 880 cm-1 region usually associated with t-butylperoxy groups. Iodometric assay showed the presence of active oxygen.
