英文摘要：

Tantalum（V） propoxide （Ta（OPr^n）5）, isopropoxide （Ta（OPr^i）5） and butoxide（Ta（OBu^n）5） were synthesized by electrochemical reactions of corresponding alcohol at sacrificial tantalum anode in the presence of tetraethylammonium chloride as a conductive additive. The pure products were isolated by reduced pressure distillation under 5 kPa. The crystal of Ta（OPr^i）5 was obtained by recrystallization from hexane at -10 ℃. These samples were characterized by Fourier transform infrared spectra （FT-IR）, Raman spectra, nuclear magnetic resonance spectra （NMR）, TG/DTA and ICP-MS. The results show that direct electrochemical synthesis of metal alkoxides has a high current efficiency and electrolysis yield. These alkoxides have a high purity of 99.97% and can be directly used as the precursor of Ta2O5 films.
