摘要：

Electrooxidation of hydroxypivalaldehyde was studied at a Ti/Sb2O5-SnO2 electrode using sulfuric acid as a supporting electrolyte in an electrolytic cell with a proton exchange membrane. The linear scan voltammograms showed the current densities at the same electrode potential increased obviously after hydroxypivalaldehyde was added, this fact indicates that the electrode has an electrocatalytic activity to hydroxypivalaldehyde oxidation. Using potentiostatic: electrolysis method, the effects of hydroxypivalaldehyde concentration, pH, temperature and anode potential on the selectivity and the current efficiency of the hydroxypivalaldehyde electrooxidation were investigated, it can be found that the effect of pH is the most obvious.
