Abstract:	本研究探討3-苯基雪梨酮在酸性溶液中( pH2.98或4.25 )電解還原反應，於添加溶有界面活性劑之EtOH或DMF溶液，所顯示的極譜行為。利用Kouteck'y方法計算所獲得的電極反應動力學參數，顯示3-苯基雪梨酮之還原為擴散所控制且為不可逆反應，隨著界面活性劑的濃度、有機溶劑含量、與pH值之增加而傾向於更不可逆。 The polarographic behaviors of the electrolytic reduction of the 3-phenylsydnone in the acidic solution (pH 2.98 or 4.25) in the presence of surfactants, dissolved in EtOH or DMF, were studied. Calculation of the kinetic parameters of the electrode reduction by the kouteckyb method revealed that the reduction of 3-phenylsydnone was of diffusion-controUed and irreversible. The tendency towards more irreversible was achieved by increasing the concentration of surfactants and the percentage of organic solvent, as well as the pH value.
