Abstract

Electrosynthesis of pinacols by using zinc tablets for the electrode and aromatic aldehydes as substrate in acid condition was performed. The influence of the current density, reaction time and hydrochloric acid concentration on pinacols yield was explored. The optimal reaction conditions were as follow: current density of 2.4 A/dm², reaction time of 60 min, hydrochloric acid concentration of 2 mol/L, the yield of pinacols was up to 14%～80%.

Key words: pinacol, electrosynthesis, zinc electrode, aromatic aldehyde, aqueous media
