摘　　要：以环戊烯为原料,采用催化剂TM 2,利用过氧化氢水溶液一步催化氧化法合成戊二醛。讨论了催化剂浓度、氧化剂浓度、溶剂种类对戊二醛收率的影响,并确定了最佳合成工艺条件:n(H2O2)∶n(C5H8)=2.05∶1.00,m(H2WO4)∶m(C5H8)=0.045∶1.000,反应温度35℃,反应时间22h,溶剂为异丙醇,戊二醛总收率65%。Pentandial was prepared by oxidation of cyclopentene using hydrogen peroxide with TM-2 as catalyst. Effects of the catalyst concentration, cyclopentene concentration,and the kinds of solvent to the recovery rate of glutaraldehyde were discussed. Optiumun sysnthetic conditions were determined as follows: n(H2O2)∶n(C5H8)=2.05∶1.00,m(H2WO4)∶m(C5H8)=0.045∶1.000; reaction temperature, 35℃; reaction time, 22?h; solvent, i-propyl alcohol. The yields of glutaraldehyde was 65%.
