| Abstract: | Cyclohexanol was synthesized into adipic acid using ammonium tungstate as catalyst and hydrogen peroxide as oxi- dant.The effects of catalyst amount,hydrogen peroxide amount and reaction temperature and time on the reaction were dis- cussed.The results showed that the yield of adipic acid could approach to 78.4% with the purity of 99.8% when the mole ratio of cyclohexanol,hydrogen peroxide and ammonium tungstate was 100:550:1 and the reaction temperature and time were 90℃and 6 h,respectively.The yield of adipic acid was stable after repeatedly using the catalyst 3 times. |
