Cyclohexanol and cyclohexanone were used in large quantity as materials for chemical products, for example, for the synthesis of adipic acid. In this paper, the process of ozonation of cyclohexanol and cyclohexanone under ultraviolet irradiation was studied. Ozonation combined with ultraviolet irradiation was used for the destruction of organic refractry in water. Cyclohexanol and cyclohexanone were readily oxidized to give adipic acid, glutalic acid, succinic acid, malonic acid, glycolic acid and their derivatives, which were further oxidized to give oxalic acid and formic acid. Simultaniously, the total organic carbon decreased effectively. By the ozonation under neutral conditions without ultraviolet irradiation, cyclohexanone was not oxidized, but cyclohexanol was oxidized to give cyclohexanone. On the basis of these results, it was found that the ozonation under ultraviolet irradiation was markedly effective for the degradation of cyclohexanol and cyclohexanone, compared with the ozonation alone.
