Structural analysis of water in ionic liquid domains – A low pressure study

• Mixtures of water and Ionic liquids fall in three distinct regions. Solvation regions can be tracked with NMR EIS measurements. Stepwise degassing ILs leads to a rearrangement between these Imidazolium-based ionic (ILs) are frequently used solvents, due their peculiar structure resulting low melting points. Recent studies revealed the direct impact molecules on self-structuring IL nano-domains. Therefore, this work influence different impurities network its vacuum stability has been studied using Nuclear Magnetic Resonance (NMR) Electrochemical Impedance Spectroscopy (EIS). As result, distinguishable interdependent could identified. Degassing solutions IL-H 2 O ratios proved strong dependence removed species initial composition doped Consequently, selective purification targeted cavities, based extraction, is proposed as novel tool control structural liquid networks presence water.
