“…Table 1. Similar results were obtained by Berezkin et al 28 The fall of current efficiency with time might be associated with the exfoliation of tantalum powders. It was noticed that plenty of black powders appeared at the bottom of the electrolyzer after long-term electrolysis, which was later confirmed to be Ta by EDS.…”

High purity tantalum ethoxide (99.997%) was successfully synthesized using electrosynthesis method and characterized by IR and 1 H-NMR spectra, the influence of various factors on the electrosynthesis process and the distillation purification of tantalum ethoxide was also studied. Cell voltage was closely related to process parameters such as electrolyte species, electrolyte concentration, electrode distance, solution temperature, current density and electrolysis time et al. All the current efficiencies were higher than 100%, which might be related to the low valence sate of tantalum. The ideal conditions for the electrosynthesis of tantalum ethoxide were also obtained. The purity of tantalum ethoxide increased when increasing reflux ratio. Infrared spectra conformed to chemical bonds excellently, and the peak area ratio of nuclear magnetic resonance coincided with number ratio of hydrogen atoms.

“…In order to avoid volatilization of n-butanol, the electrolysis was performed at 65-70°C. 16,21 The increase of cell voltage with time at later stage might be associated with the exfoliation of zirconium powders. It was noticed that plenty of black powder appeared at the surface of the zirconium plate after a long-term electrolysis, which was later confirmed to be Zr by EDS (not shown here).…”

Zirconium n-butoxide was successfully synthesized using electrochemical method and characterized by IR and 1 H-NMR spectra. The influence of various factors on the cell voltage of electrosynthesis process was studied. The cell voltage increased with an increase of electrode distance and current density, but decreased with the increasing Bu n 4 NBr concentration and solution temperature. The ideal conditions for electrosynthesis of zirconium n-butoxide were obtained. The resulting zirconium n-butoxide solution was purified by distillation and n-hexane extraction. Infrared spectra conformed to chemical bonds excellently, and the peak area ratio of nuclear magnetic resonance coincided with number ratio of hydrogen atoms in Zr(OC 4 H 9 ) 4 . The purity was close to 99.99%.

“…17 Apart from some studies on the electrochemical synthesis of hafnium alkoxides, to the author's knowledge, few reports have related to the electrochemical behavior of the electrosynthesis of hafnium alkoxides. [18][19][20][21] In the present study, the electrochemical behavior of Hf was investigated in anhydrous ethanol containing supporting electrolytes using potentiodynamic polarization, cyclic voltammetry, chronoamperometry, impedance and SEM techniques, which are instrumental in understanding the reaction mechanism.…”
