| 摘 要： | 以二硫化碳和水合肼为原料合成了2,5-二巯基-1,3,4-噻二唑(DMcT),并通过元素分析、Raman光谱和红外(IR)光谱对DMcT的结构进行了表征。DMcT的两对氧化还原峰电位差分别为0.96V和1.33V,这表明在室温下氧化还原反应速度很慢。酸碱对DMcT氧化还原反应有很大的影响:加入三乙胺之后,DMcT的氧化反应更加容易,还原峰电流增加,但对还原峰电位影响不大;相反,甲磺酸存在时,DMcT的氧化反应更难进行,而还原反应变得更加容易。

| Abstract: | 2,5-dimercapto-1,3,4-thiadiazole(DMcT) was synthesized by hydrazine hydrate and carbon disulfide. The structure of DMcT was determined by elemental analysis, Raman spectra and infrared spectra. The difference of two pairs of redox peak potential was 0.96 V and 1.33 V(vs. Li/Li+), respectively, which indicated that the redox reaction of DMcT was rather slow at room temperature. The influence of acidic and basic condition on the redox behavior of DMcT was studied. The addition of triethylamine facilitated the... |
