中文摘要 | 本研究是探討組對電還原丁醛,及氧化?喃的情形。利用改變電流密度、溫度、電極材料、還原媒子以及反應物材料等因子,討論這些因子對電流效率及能量損失之影響。影響組對電解之電流效率之主要因素為電流密度及電極材料,而其次要因素則為溫度及反應物濃度。影響陽極主要產物2,5- dimethyoxy- 2,5-dihydrofuran,及陰極主要產物丁醇之電流密度的主要及次要原因是不同的。結果最高總電流效率可達155.4%,而其最低的能量消耗達 2.69 kW.h.kg¯¹。 |
英文摘要 | Mediated cathodic reduction of butyraldehyde and anodic oxidation of furan by paired electrolysis were studied. The effects of the current density, temperature, electrode materials, redox mediator, and reactant concentrations on the current efficiency and power consumption were determined. The main factors which affected the current efficiency of the paired electrolysis were the current density, redox mediator concentration, and electrode material, while the minor factors were the temperature and reactant concentration. The effects of the major and minor factors on the current efficiencies of the main products: 2,5-dimethyoxy-2,5-dihydrofuran, at the anode and butyl alcohol at the cathode, respectively, varied. The highest total current efficiency and the lowest power consumption of paired electrolysis were 155.4% and 2.69 kW.h.kg¯¹, respectively. |
