| Abstract: | Adipic acid was synthesized by Ammonium tungstate catalyzed oxidation of cyclohexene 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,i.e.when n（cyclohexene）：n（hydrogen peroxide）：n（ammonium tungstate） was100：440：1,and the reaction temperature was 92℃,the reaction time was 6 h,the isolated yield of adipic acid could reach 81.4%and its purity was 99.8%.The catalyst could be reused for 3 times and the isolated yield of adipic acid was still stable. |
