摘　　要：该文考察了羟基新戊酸直接电合成工艺中电流密度和槽压两个重要参数。通过稳态极化曲线,考察了羟基新戊醛浓度、pH及温度对电氧化羟基新戊醛的电流密度影响。比较了同一电流密度下,有隔膜电解槽和无隔膜电解槽的槽压。结果显示,反应温度、硫酸浓度对电流密度影响较大;同一电流密度下,无隔膜槽的槽压明显低于有隔膜槽的槽压,表明无隔膜槽的能耗要小于有隔膜槽的能耗。Direct electrooxidation of hydroxypivalaldehyde was investigated by steady state polarization curves in sulfuric acid solution. The change trends of current density with the concentration of hydroxypivalaldehyde, pH and reaction temperature were studied. The results showed that the effects of reaction temperature and pH were most prominent. The cell voltage with proton exchange membrane was obviously higher than that without proton exchange membrane at the same current density.
