摘要：

Glyoxylic acid is an important intermediate in organic synthesis. Its production by electroreduction of oxalic acid is very well known. However, attempts to scale up the process have failed due to rapid deactivation of the cathode. In this paper a process for overcoming this problem is described. The cathode activity can be continuously restored by adding small amounts of a Pb(II) salt in both anolyte and catholyte. In this way, the process has been continuously run for more than 300 h with a current efficiency of 92% and a selectivity higher than 95%.
