| Abstract Scope |
Deep eutectic solvents (DESs) are promising green alternatives to volatile organic solvents due to low toxicity and cost. This study develops novel Mg-containing DESs using MgCl2 as the solute, choline chloride (ChCl) as the hydrogen-bond acceptor (HBA) and either 1,3-propanediol or 1,2-butanediol as the hydrogen-bond donor (HBD). The solubility of MgCl2 in ChCl-diol systems at various molar ratios was determined. Properties including density, viscosity, conductivity, and cyclic voltammetry behavior were measured from 313 K to 373 K. Results show: solubility and density exhibit linear relationships with temperature; the logarithm of conductivity and the logarithm of viscosity are linearly related to 1/T. The MgCl2-ChCl-1,2-butanediol system demonstrated superior performance at 353 K, exhibiting a conductivity of 2.73 mS·cm-1, a viscosity of 87 mPa·s, and an electrochemical stability window of 1.8 V. This novel Mg-DES offers a potential electrolyte for Mg electrodeposition. |
