摘要

本文报道采用石墨电极直接电氧化D_葡萄糖酸钠(NaGL)合成D_阿拉伯糖研究结果.研究了葡萄糖酸钠浓度、电解电压、温度及电解液组成对电流效率和合成产率的影响。同时指出采用液体电解池进行恒电位电解,其效果比恒电流电解法更好

Abstract

D Arabinose synthesized by direct electro_oxidative decarboxylation of D gluconate on graphite electrode from aqueous solutions. The effects of D gluconate concentration, electrolysis potential, temperature and electrolyte composition on the current efficiency and product yield of electrosynthsis are discussed. The laboratory scale electrosynthesis was achieved with flow through cell.The optimum technology conditions for electrosynthesis were obtained with orthogonal design method.Both galvanostatic and potentionstatic conditions have been exploited, the later was found to be more effective.
