dc.description.abstractThe aim of the study is to determine the effect of process parameters on dielectric properties of deep eutectic solvents (DESs), which have been widely used in recent years. In this study, DESs were prepared using choline-chloride as the hydrogen-bond acceptor and glycerol, formic acid and acetic acid as the hydrogen-bond donor. The effect of different process parameters such as molar ratio (1:2, 1:3 and 1:4), water content (15%, 30% and 45%), temperature (25, 50 and 75 degrees C) and frequency on dielectric properties of the DESs were examined. The highest dielectric constant values were found to be 38.13 +/- 0.54, 44.96 +/- 0.07 and 46.74 +/- 0.02 for glycerol, formic acid and acetic acid, respectively for the process conditions of 25 degrees C temperature, 45% water content and 1:4 molar ratio (at 2450 MHz). Moreover, for all DESs, it was found that a decrease in water content resulted in a decrease in both dielectric constant and loss factor values. This can be explained by the absence of free water molecules which are responsible from dipole rotation mechanism. In light of the results, if DES will be used in microwave processes, formic or acetic acid containing DESs might give more successful results compared to the ones with glycerol.en_US
