环氧苯乙烷的水相电化学还原反应

Study on electrochemical reduction of styrene oxide in aqueous media

以高效、绿色环保为目标,开展了"探索性实验"项目——环氧苯乙烷水相电化学还原反应。实验采用微量化反应,水为溶剂,以Zn-Zn为电极体系,电子作为氧化剂或还原剂,利用现场制备的具有三维空间结构的纳米锌,将环氧苯乙烷还原成苯乙烯目标产物。通过气相色谱、1 H NMR和13 C NMR等手段对产物进行表征并验证,产率达到95%。将该科研成果引入本科生实验教学,学生通过接触科学前沿以提高学习兴趣,培养学生的科研素质和增强学生的科研能力,教学效果好。

This paper describes a highly efficient and environmental friendly organic experiment, i. e. , the electrochemical reduction of styrene oxide in aqueous media, which was designed for the undergraduate explorative teaching. The reaction was carried out in a small scale, taking Zn as anode and cathode in aqueous media. The styrene oxide was reduced to styrene employing electons as redox reagents. Through determination by GC, 1H NMR and 13C NMR, the yield was as high as 95%. By introducing the novel research result into undergraduate teaching, the interest and the capability of the students on the research are increased, which can obtain a good course evaluation.
