摘要

本研究探討－溫和的條件下(298 K, 1 atm)組對電解丙酮生成二丙酮醇之反應，實驗結果証實影響二丙酮醇電產率之主要因素有通電量、電解質種類、水濃度、操作型式及電流密度等因素。此外陽極材料對於電流效率影響較小。於最佳操作條件之下，生成二丙酮醇之選擇性為100%，並無醇醛縮合之副產物生成，而且生成二丙酮醇的電產率高達850 g•F^(-1)。

The paired electrolysis of acetone to produce diacetone alcohol (daa) under mild conditions (298 K, 1 atm) was explored. The results revealed that the main factors that affected the yield rate of daa were the coulombs of electricity passed, supporting electrolyte, amount of H2O, operating type, and current density, and that a minor factor affecting the yield rate of daa was the anode material. Under optimal conditions, no further condensation products other than daa in acetone self-condensation could be observed; i.e., the selectivity of daa was 100%, and the yield rate of daa was up to 850 g•F^(-1).
