162.3 g (1 mol) of cyclododecatriene (purity 95%) were dissolved in 1500 ml of methanol, the solution was cooled to -20° C., and an O3 /O2 mixture containing 4% by weight of O3 was passed in until 0.33 mol of ozone had been introduced into the solution. The hydrogenation solution obtained as in Example 1 contained dodecanedial and its acetals. Cyclododecane formed was extracted from the acetic acid solution using petroleum ether prior to the oxidation.
