• 中文摘要： 本研究乃在一隔離槽中陰陽極組對生成氫氧根及氫離子同時催化丙酮生成二丙酮醇。探討各種影響陰陽極組對電解反應之因素。實驗結果證明間段式電解比連續式電解為佳。陰極反應速率比陽極快,丙酮濃度由2M增加到8M時,二丙酮醇的產率由100g/F增加到800g/F。二丙酮醇的選擇性幾乎100%。在30.degree.C、8M丙酮濃度及0.2M的氯化鈉濃度時,二丙酮醇的最佳產率為1,300g/F。
• 英文摘要： Paired electrolysis of acetone in a divided cell was carried out in this present work. Proton H/sup +/ and OH/sup -/ anions were simultaneously generated at anode and cathode, respectively, by paired electrolysis. Acetone was catalytically condensed to form diacetone alcohol (daa). The factors which affected both anodic and cathodic reactions were obtained. Interrupt electrolysis being more preferable than that of continuous electrolysis was confirmed by the observed results. The reaction rate of aldol condensation at cathode was observed to be faster than that at anode. The yield of daa increased from 100 to 800g/F with increasing concentration of acetone from 2 to 8M. The selectivity of data was found to almost reach 100% with the best yield of daa occurring 1,300g/F at 8M acetone, 0.2M NaCl and 30.degree.C.
