| Research Abstract |
We have investigated the ionic salvations to formic acid, water, and benzene molecules in ionic liquids by means of the nuclear magnetic resonance. Formic acid is stabilized by ions and formed from hydrogen and carbon dioxide in ionic liquids. Water molecules are solvated by strong acids existing as impurities and double recrystallization can remove the strong acids. We have shown by means of the nuclear Overhauser effect measurement that such a polar solute as water is interacted with a hydrogen atom at site-2 in the imidazolium ring while such a non-polar solute as benzene is parallel to the imidazolium ring.
