Abstract:	本實驗乃在一隔離槽中進行，以陰陽極組對同時電解產生氫質子及氫氧根離子，進而催化丙酮形成二丙酮醇，探討各種影響組對電解丙酮反應的因素。結果證明，間斷式電解法較連續式佳，力且陰極槽中之反應速率較陽極槽中之縮合反應快。當丙酮濃度由2M增加至8M時，二丙酮醇的產率由100gF-1 增加至800gF-1，溫度為30。C時8M的丙酮及0.2M NaCl濃度下，最佳產率為1300gF-1。 Paired electrolysis of acetone in a divided cell was carried out in this study. Protone H+ and OH- anion 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 re-actions were explored. The results indicate that interrupt electrolysis is better than that of continuous electrolysis. The reaction rate of aldol condensation at cathode is faster than that at anode. The yield of daa increase from 100 to 800 g/F with increasing concentration of acetone from 2 to 8 M. The selectivity of daa almost reaches 100% and the yield of daa was 120 g/F during 120 coul electricity passed.
