| Popis: | In this study, the Deep Eutectic Solvent (DES) is prepared based on glycerol and polyethylene glycol 600 (PEG) as hydrogen bond donor and choline chloride (ChCl) as hydrogen bond acceptor. The glycerol based DESs were formed with ratio of 1:2, 1:3, 1:4 and 1:5 whereas three-component DESs of ChCl, PEG and glycerol were synthesized with ratio 1:3:2, 1:4:2 and 1:5:2. The DESs were subjected to DSC, Karl Fishcer, thermal conductivity, viscosity and density testing. The melting temperature (Tm) for PEG based DESs were found to in the region of 18 °C. The moisture content in DESs were identified through Karl Fishcer testing was found to be |
