The Reaction between K2CO3 and Ethylene Glycol in Deep Eutectic Solvents
Understanding intermolecular interactions is important for the design of deep eutectic solvents. Herein, potassium carbonate (K<sub>2</sub>CO<sub>3</sub>) and ethylene glycol (EG) are used to form deep eutectic solvents. The interactions between K<sub>2</sub>CO<sub>3</sub> and EG are studied using nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectra. Interestingly, the interaction results indicate that the carbonate anion CO32- can react with EG to form EG-based organic carbonate, which can occur even at room temperature. The possible reaction steps between K<sub>2</sub>CO<sub>3</sub> and EG are presented. As K<sub>2</sub>CO<sub>3</sub> can be prepared from CO<sub>2</sub> and KOH, the findings of this work may provide a promising strategy for CO<sub>2</sub> capture and conversion.
