| Abstract: | The electrolytic reduction of Oxalic and salicylic acids to the corresponding aldehyes was researched many times by the polarography.It was showed by those experiment that the reduction reactions are irresersible at Hygcathode,reduction potential was -1.60V~-1.70V(vs.SCE).Glyoxylic Acid and Salicylaldehyde was obtained by electrolytic synthesis at the Cu-Hg cathode.the current efficiency was 55.0~60.0%. |
