Two oxidation products of the reaction of C60 with O3 in toluene or dichlorobenzene were obtained in dependence on the amount of ozone absorbed by the solution and the reaction time. The short time oxidized product is insoluble in common organic solvents and water, but the water-soluble derivatives were obtained after hydrolysis under a basic condition. It′s IR spectrum is similar with that of C60 polyhydric derivatives. The extensive oxidation product of C60 is water-soluble without any further dispose. The structures of the two oxidized products were characterized by variable-temperature FTIR, XPS, elementary analysis, TGA and TOF-MS, ESI-MS, FAB-MS technique. Both products are thermally unstable, H2O, CO and CO2 are eliminated during the increase of temperature.%在C60的甲苯或二氯苯溶液中通入O3，通过改变O3的吸收量及反应时间可得到两种氧化产物. 一种产物在有机溶剂及水中均不溶，但经碱性水解后得到水溶性产物，其红外光谱与C60羟基化合物相似；在长时间通O3条件下，得到水溶性的C60氧化产物. 用变温红外光谱、 XPS、元素分析、热谱和质谱研究了氧化产物的可能结构，发现生成的C60氧化产物对热不稳定，随着温度升高，有CO2， CO和H2O放出.
