Solvent effects of 1-Ethyl-3-methylimidazolium acetate — •Volker Lesch¹, Andreas Heuer¹, Christian Holm², and Jens Smiatek² — ¹Institut für physikalische Chemie, Westfälische Wilhelms-Universität Münster — ²Institut für Computerphysik, Universität Stuttgart

Room temperature ionic liquids (RTILs) are promising candidates for several applications due to their properties with regard to thermal stability and ionic dissociation. For example the usage as electrolytes or solvents is investigated. Furthermore, they are less hazardous compared to other solvents.

In this study, we focus on solvation effects of 1-ethyl-3-methylimidazolium acetate. Therefore, we conducted molecular dynamics simulations of this ionic liquid combined with uncharged and charged spheres. We investigated the solvation behavior and the dynamics of the spheres. We found perturbation in the ordering of the ionic liquids also for long distances, even for the neutral sphere. The reason for this perturbation are electrostatic interactions.
