In this process, the electrolylic bath with cationic exchange membrance and leas electrode is used. The cathode liquor is oxalic acid, the anode liquor is diluted sulfuric acid. The process above has following advantages with high yield, top quality, lower cost, no "three wastes" pollution, and no oxalic aldehyde in the product. It is a cleaner and environment-friend technology, and is a development trend for production of glyoxalic acid. Complete analytical process for raw materials, intermediate and final products were established.

本论文通过对乙醛酸合成路线的研究，确定了草酸电解法制乙醛酸的工艺路线，此法采用装有阳离子交换隔膜和铅电极的电解槽，阴极电解液为草酸溶液，阳极电解液为稀硫酸，该工艺具有产品收率高、质量好、成本低、无三废污染、产品中无乙二醛等特点，是一条清洁、绿色工艺，是生产乙醛酸的主要发展方向。

The nanocrystalline film was composed of a three-diminsional network of interconnected particles.Reodx behavior and electrocatalytic activities of the Ti/nano-TiO2 electrode were investigated by cyclic voltammetry from oxalic acid and nitrobenzene to glyoxalic acid and p-aminionphenol.
