A mixed solution consisting of 20.7 g of dimethyl sulfoxide and 1.6 g of p-toluenesulfonic acid was kept at 20° C., to which was added dropwise another mixed solution consisting of 37.3 g of 3,3,5-trimethyl-cylcohexanone-dimethylacetal and 23.8 g of 1,1-dimethylbutyl hydroperoxide. The resulting solution had an acid concentration of 0.1 mol/kg of the solution. The solution was treated in the same manner as described in Example 1 to obtain 50.3 g (yield: 68%) of crude 1-methoxy-1-(1,1-dimethylbutylperoxy)-3,3,5-trimethylcyclohexane having a purity of 75%. The resulting crude peroxyketal was distilled at 68°-72° C. under a vacuum of 0.005 mmHg to obtain a purified peroxyketal having a purity of 96%.
