Reaktionsschritte
A mixed solution consisting of 15.9 g of dimethyl sulfoxide and 1.2 g of p-toluenesulfonic acid was kept at 20° C., into which was added dropwise another solution consisting of 29.1 g of cyclohexanone-dimethylacetal and 21.1 g of 1,1-dimethylpropyl 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 33.8 g (yield: 67%) of crude 1-methoxy-1-(1,1-dimethylpropylperoxy)cyclohexane having a purity of 86%. The resulting crude peroxyketal was distilled at 43°-45° C. under a vacuum of 0.1 mmHg to obtain a purified peroxyketal having a purity of 98%.
