Procedure

A jacketed reactor equipped with a mechanical stirrer, a thermometer and a dropping funnel was charged with 9.3 g (0.075 mole) of 45% KOH, 4.7 g of water and 11.3 g (0.058 mole) of 97.3% 7-hydroxy-1,1,5-trimethylheptyl hydroperoxide. To this vigorously stirred solution at 30° C. was slowly added 6.4 g (0.050 mole) of 94.3% pivaloyl chloride over a period of 20 minutes. The resulting mixture was then vigorously stirred for one hour at 30° C. after which it was cooled to 15° C. and 100 ml of pentane and 25 ml of water were added. After separating and discarding the aqueous phase the product solution was washed at 10° to 15° C. with 20 g of buffered sodium sulfite solution (consisting of 0.8 g of acetic acid, 1.2 g of sodium acetate, 2.0 g of sodium sulfite and 16 g of water), with 15 ml of water and then with 20 g of 7.7% sodium hydrogen carbonate solution. The resulting pentane solution was then dried over anhydrous MgSO4 and after separation of the spent desiccant by filtration the pentane was removed in vacuo at 0° to 10° C. leaving 8.2 g of liquid product. The assay of the product according to peroxyester active oxygen was 69.6% and the corrected yield was 41.7%. An infrared spectrum of the product showed a strong, broad OH band centered at 3400 to 3500 cm-1.
