Aspects of the Electrosynthesis of 2-Hydroxymethylpyridine

  • A. M. Romulus
  • A. Savall


The electrochemical reduction of 2-ethylpicolinate (A) in a sulfuric acid medium was studied on a lead cathode during electrolyses in a laboratory filter press reactor under galvanostatic conditions. The yield of the conversion of (A) to the corresponding 2-formylpyridine (B), 2-hydroxymethylpyridine (C) and picoline (D) was investigated as a function of the medium acidity, current density, concentration of (A) and temperature.

A reaction model including the three electrochemical steps: A → B → C → D is presented. The variations of the charge transfer constants are considered as functions of the reactant conversion and mass transport resistance is integrated. The simulation gives a reasonable description of the behaviour of this complex electrochemical process.
