摘要

应用间接氧化法,以Pb为阳极,BrO3-/Br-为氧化媒介,电氧化淀粉制备双醛淀粉.研究了温度、硫酸与淀粉浓度对电合成过程的影响.在35℃,阳极液WNaBr=2%,CH2SO4=0.05 mol/L,W淀粉=10%,电流密度15 mA/cm2的实验条件下,电流效率为50%.

Abstract

In this paper,Nafion membrane was used as the separator in the electrolysis cell to indirectly electro-generating the double aldehyde starch(DAS) with BrO-3/Br-as a redox mediator and Pb as an anode.Effects of temperature,concentration of sulfuric acid and starch on the electro-oxidation of DAS were discussed.The steady state polarization curves were obtained.The experiment results showed that the current efficiency was over 50% when the electrolysis current density was 15mA/ cm2.
