研究了'牺牲'阳极法电化学合成乙醇钽过程中,添加剂种类与浓度、电解液温度、阴阳极极距和电流密度的影响.选取最佳合成条件为:四甲基氯化铵0.04 mol/L,温度为电解液的沸腾温度,极距约2 cm,电流密度220 A/m2.电合成的混合液经常压蒸馏和减压蒸馏,得到产品用红外光谱、拉曼光谱和元素分析进行表征,确定了产品为乙醇钽.电合成的电流效率大于95%,产品蒸馏时钽的直收率82.8%.

英文摘要：

The effects of additive species, additive concentration, temperature, anode to cathode distance and current density on the electrochemical synthesis of tantalum ethoxide using sacrificing anode method have been investigated. The optimum conditions were tetramethylammonium chloride 0.04 mol/L, boiling temperature, distance 2 cm and current-density 220 A/m(2). After treating the mixed solution with general distillation and reduced distillation, the final product were characterized by fourier transform infrared(FTIR) spectrum, Raman spectra and elemental analyses. The product is tantalum penta-ethoxide. Current efficiency is more than 95%, and recovery ratio of tantalum during distillation is 82.8%.
