| 摘 要： | 以环己烯为原料,w(H2O2)=30%的过氧化氢为氧化剂,在草酸(H2C2O4)作为助剂的条件下,采用磷钨酸(H3PW12O40)作催化剂合成己二酸,结果表明,当n(环己烯)∶n(H3PW12O40)∶n(H2C2O4)∶n(H2O2)=100∶1∶1∶538,反应温度为92℃,反应时间为6h时,己二酸的收率可达70 1%。讨论了H3PW12O40加入量、环己烯加入量、过氧化氢加入量、反应时间、反应温度等因素对反应的影响。

Synthesis of Adipic Acid Catalyzed by H3PW12O40 |
| |
| Abstract: | Using w(H2O2)=30% aqueous hydrogen peroxide as oxidant,oxalic acid (H2C2O4) as cocatalyst,adipic acid was synthesized with cyclohexene as raw material and phosphotungstic acid (H3PW12O40) as catalyst.When n(cyclohexene)∶n(H3PW12O40)∶n(H2C2O4)∶n(H2O2)=100∶1∶1∶538,reaction temperature was 92 ℃ and reaction time 6 h,the yield of adipic acid was up to 701%.Influences of the amount of H3PW12O40,cyclohexene and hydrogen peroxide,reaction time and reaction temperature were also discussed. |
