| Abstract: | Adipic acid was synthesized by WO3 catalyzed oxidation of cyclohexanol with 30% hydrogen peroxide. The influence of reaction conditions such as catalyst amount, hydrogen peroxide amount, reaction temperature and time on the oxidation was investigated. Under the optimal conditions that n （cyclohexanol） ：n （ hydrogen peroxide） ：n （ tungsten trioxide） was 100：600：4, the reaction temperature was 100℃ and the reaction time was 6 h, the isolated yield of adipic acid could reach 67.6% and the purity was 99.8%. The catalyst could be reused for 5 times and the isolated yield of adipic acid was still above 60.2%. |
