Direct electrochemical preparation of titanium alkoxides

Titanium ethoxide was directly prepared using titanium as sacrificial anode in absolute ethanol.The product was characterized by Raman spectra and elementary analysis.The influence of temparture,conductive additives and trace of water on product yield was also investigated.The optimum operating conditions established were current density of 300 A·m -2 ,anode pofential of 2 V(vs SCE) and cell temperature of 60-70 ℃.Bu 4NBr was selected as conductive additive.The current efficiency could reach 88 7%.Preventing titanium anode from being passiviated can improve the product yield.
