All of the studies of glycerol/ChCl deep eutectic mixtures have been
carried out using pure glycerol as a starting material. However, given
the glut of waste glycerol on the market from biodiesel preparation,
using waste glycerol as the HBD in DESs could reduce waste from biodiesel
preparation, provide a value-added product for biodiesel manufacturers,
and generate a “green” solvent that could potentially be
used in chemical reactions. Herein,we investigate the use ofwaste glycerol
from biodiesel preparations as the HBD in glycerol/ChCl DESs.
