Procedure

A mixture of 19.60 g. (0.20 mole) of mesityl oxide, 36.90 g. (0.25 mole) of 3-hydroxy-1,1-dimethylbutyl hydroperoxide (90%) and 10 g. of Amberlyst 15® sulfuric acid type ion exchange resin was stirred for 16 hours at 30° C. The resin was separated by filtration and the filtrate subjected to steam distillation at 20 torr in the presence of sodium bicarbonate to maintain a slightly alkaline pH during the distillation. The distillation was ended when the removal of unreacted mesityl oxide was complete.
