Abstract—Deep Eutectic Solvents (DES) are emerging as new
class of green solvents with the favorable properties of low cost,
minimum volatility, biodegradability and suitability for many
industrial applications. In an attempt to synthesize a new class
of DES, potassium carbonate was used as a salt with glycerol as
a hydrogen bond donor (HDB). The basic physical properties of
this DES were measured at different temperatures and
salt:HBD molar ratios. The physical properties measured
included density, viscosity, surface tension, refractive index and
pH at a temperature range of 20 - 80 oC. The system didn’t show
a freezing points in DSC thermograms, however glass transition
temperatures were observed. This system exhibits similar
physico-chemical properties to other reported DES. The values
of these properties indicated that the prepared DES may have
great potential for industrial applications.
