Preliminary study of one-pot electrochemical conversion of citronellal using platinum electrode.

A preliminary study of electrochemically citronellal conversion has been studied for the first time in a one-pot (single chamber) electrolytic cell using a platinum working electrode. This study aims to develop a facile citronellal conversion method to produce more valuable derivative products. Linear sweep voltammetry was performed in the various ethanol mixture electrolytes (0.1 M HCl, KCl, and NaOH) from 0.5 to -1.5 V vs Ag/AgCl at a scan rate of 100 mV/s to evaluate the reduction peaks of citronellal. A peak at -0.5 V vs Ag/AgCl was observed using the ethanol+0.1 M KCl mixture electrolyte predicted as a reduction peak of citronellal. Furthermore, a reduction product was evaluated using chronoamperometry technique at a constant potential of -0.5 V vs Ag/AgCl for 2 hours produced menthol (46.92%), isopulegol (32.12%), and p-menthane-1,3-diol (20.96%) as the products. This result revealed a potency of electrochemically citronellal conversion conducted in a simple one-pot electrolytic cell. [ABSTRACT FROM AUTHOR]
