研究以自制的Zn PTFE复合电极为阴极电合成频那醇 (2 ,3 二甲基 2 ,3 丁二醇 )。探讨了复合电极中PTFE含量、阴极电流密度、电解液温度、电解电量对频那醇产率的影响。实验结果表明 ,以Zn PTFE(PTFE 6 2 5 (wt) % )复合电极为阴极 ,当阴极电流密度为 2 5A·dm-2 、电解液温度为 1 5℃、电解至理论电量的 1 4 0 %时 ,电合成频那醇的产率可达 5 3 6% ,产品的红外谱图与标准谱图相符。 In the present study, pinacol (2,3-dimethyl-2,3-butanediol) was electrochemically synthesized from a homemade Zn PTFE composite electrode. The effects of PTFE content, cathodic current density, electrolyte temperature and electrolysis capacity on the yield of pinacol were discussed. The experimental results show that when the composite electrode of Zn PTFE (PTFE 6 2 5 (wt)%) is used as the cathode, when the cathode current density is 2 5A · dm-2, the electrolyte temperature is 15 ℃, %, The yield of electrosynthesis pinacol can reach 536%. The infrared spectrum of the product is consistent with the standard chromatogram.
