摘要


有鑑於維生素B12對有機鹵化物的電催化分解潛力,本論文尋求維生素B12結構類似物,以模擬其在分解有機鹵化合物,如2,3-雙溴丁烷、1,2-雙溴丁烷、1,2-雙溴環己烷、和二氯丙酸鈉方面的應用潛力。實驗結果顯示:若以玻璃碳電極對2,3-雙溴丁烷進行還原分解時,須給予-1.6 V vs. SCE的電壓始能達到分解目的,然若在溶液中或在電極上加入含鈷化合物,如(1R,2R)-(-)-1,2-cyclohexanediamino-N-N'-bis(3,5-di-t-butylsalicylidene)Cobalt (IΠ),則可於較正電位將2,3-雙溴丁烷還原分解成低毒性的產物:烯與溴離子。我們也藉由紅外線吸收光譜與電化學交流阻抗進行分析,其結果均證實含鈷化合物確實具有催化分解有機鹵化物的應用潛力。

The reduction of organic dibromides, such as 2,3-dibromobutane (2,3-DBB), 1,2-dibromobutane (1,2-DBB) and 1,2-dibromocyclohexane, exists with cathodic barrier, which can only be reduced at a potential more negative than -1.6 V vs. SCE with bare carbon electrodes in most aprotic media. While, as cobalt complexes such as (1R,2R)-(-)-1,2-cyclohexanediamino-N-N'-bis(3,5-di-t-butylsalicylidene) Cobalt (III) were incorporated, the barrier could be significantly reduced. Organic dibromides or dichlorides could thus be decomposed into less toxic products: alkenes and the associated halide ions. IR spectral analysis and EIS analysis confirmed these results, suggesting that cobalt complexes are promising green catalysts for the degradation of organic halogen wastes.
