中文摘要：

研究了8-羟基喹啉对丙酮中V2O5催化氧化环己烯合成环己烯酮的调变作用,考察了8-羟基喹啉的用量、反应温度、反应时间、溶剂和催化剂用量对环己烯氧化反应的影响,发现在该催化体系中生成的环己烯醇和环氧环己烷可转化成环己烯酮,在适当的反应条件下可抑制环己烯醇和环氧环己烷的生成.结果表明,当五氧化二钒的用量为1%,五氧化二钒与8-羟基喹啉之比为1∶2,在20℃以下反应时,过氧化氢几乎定向地将环己烯氧化成环己烯酮.认为是8-羟基喹啉与钒的配位作用促进了环己烯酮的生成.

英文摘要：

The modification effect of 8-hydroxyquinoline on oxidation of cyclohexene to 2-cyclohexen-l-one catalyzed by V2 O5 with acetone as solvent was studied. The effects of 8-hydroxyquinoline amount, reaction temperature and time, and amounts of solvent and catalyst on the reaction were investigated. It was found that the two kinds of products, 2-cyclohexen-l-ol and cyclohexene oxide from the cyclohexene oxidation were converted to 2-cyclohexen- 1-one and were inhibited at the proper reaction condition in the catalytic system. The results showed that the directional oxidation of cyclohexene to 2-cyclohexen-1-one was almost completed by hydrogen peroxide under the conditions of the molar rate of V2O5 to cyclohexene being 1： 100 and V2O5 to 8-hydroxyquinoline being 1： 1 or reacting eomplexation 8-hydroxyquinoline to vanadium.
