Abstract

In this study, electrochemical valorization of glycerol was conductedin a two-compartmentelectrolysis cell. This novel method consisted of two steps; glycerol was first treated by concentrated sulphuric acid for dehydration to favour the electron transfer then was subjected to electrolysis. The glycerol conversion in the dehydration process was optimized using the Design of Experiment (DOE) methodology by studying the effect of reaction temperature, reaction time and mole ratio acid to glycerol. During the glycerol dehydration and electrochemical process, various high potential added-value compounds were produced such as glycerol acetal, glycerol ether and diethyl succinate. The possible reaction mechanismsfor the formation of these added-value chemicals are also proposed.
