Indirect Electro-synthesis 2,3-epoxysuccinic Acid by Bi-mediums (H2O2/O2,VO(acac)2OOH/VO(acac)2)

摘要/Abstract

摘要:

用H2O2/O2,VO(acac)2OOH/VO(acac)2作氧化还原媒质电合成环氧丁二酸,研究了pH、电流密度、媒质的初始浓度及温度对电合成环氧丁二酸电流效率的影响,其最佳工艺条件是:电流密度1 mA/cm2,pH=7,温度30~50℃,VO(acac)2OOH/VO(acac)2的初始浓度0.5 mmol/L.在此条件下平均电流效率为61%.

Abstract:

The experiment study electro-organic synthesis of 2,3-epoxysuccinic acid by bi-mediums of oxidating-reducing H2O2/O2,VO(acac)2OOH/VO(acac)2 and study the effect of the pH,electrolysis temperation current density,concentration of mediums,temperature on the current efficiency.The optimum productive condition,that is pH=7,temperature 30~50℃,current density 1 mA/cm2.The average current efficiency was 61%.
