【Abstract】 The electrochemical behavior of the Mg electrode in ethanol was investigated. Magnesium complexes Mg(OEt) 2- x (acac) x , Mg(OBu) 2- x (acac) x were directly prepared by electrochemical dissolution of Magnesium in non-aqueous media. The products were characterized by FT-IR spectra and Raman spectrum. The influence of the temperature and concentration of conductive additive on product yield were also investigated. The experiments showed that the temperature controlled under 40～50*!℃, and concentration of Bu 4NBr of 0.04～0.05*!mol/L as conductive additive could improve current efficiency and electrolysis yield. These Magnesium complexes with high purity could be directly used as precursors of nanometer oxides.更多还原
