Is the ionic liquid 1-ethyl-3-methylimidazolium methanesulfonate [emim][MeSO3] capable of rigidly binding water?

► Properties of water - [emim][MeSO3] as a function of composition and temperature. ► Activation energies are linear to water mole fraction. ► Diffusion does not follow Stokes-Einstein law. ► Structural domains may stay intact up to water mole fraction = 0.9. ► Water is structurally shielded from interfering with water sensitive reactions.
