Aqueous N-H acid bis(trifluoromethylsulfonyl) imide Solution - [C4mim][Tf2N] Ionic Liquid Biphasic System: an Original Investigation by Diffusion Ordered Spectroscopy Nuclear Magnetic Resonance

Transfers of solutes from an aqueous solution to ionic liquid and vice versa has been well studied for years. On the other hand, influence transferred on liquid's network is not yet evaluated. Therefore, we focus - biphasic system composed two immiscible solutions containing N-H acid bis(trifluoromethylsulfonyl) imide [C4mim][Tf2N] liquid. After mixing separation phases, a part water, H3O+, [Tf2N−] H[Tf2N] anions are into because salting in effect. The presence this might modify local structure So far, our goal evaluate structural change using several tools. For this, one dimensional 1H, 19F Diffusion Ordered Spectroscopy Nuclear Magnetic Resonance were carried out We observed that some water molecules free formed microstructure as pocket inside network. others hydrogen bonded Tf2N−….H-O-D….Tf2N− example. As long mole fraction remains less than or equal [C4mim+] maintained. Free moves at its own speed bound inclusion soon greater [Tf2N−], gradually dislocated. Charged clusters with [C4mim+], bond build flow between them.
