摘要
以WO3为催化剂,H2O2氧化环己醇合成己二酸。探讨了催化剂用量、H2O2用量、反应温度和时间等条件对反应的影响。优化条件:n(环己醇)∶n(H2O2)∶n(WO3)=100∶600∶4、反应温度100℃、反应时间6h。己二酸分离收率达67.6%,纯度99.8%;催化剂重复使用5次后,己二酸收率仍可达60.2%。
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%.
