Molecular mobility and isotopic exchange in aqueous and alcohol solutions of [Cnmim]Cl,Br type ionic liquid.
S. A. Dontsov

Investigation of molecular mobility and isotopic exchange in ionic liquid [С8mim]Cl (1-oktil-3-metilimidazolium chloride) solutions  in heavy water (D2O) was made. Were selected for study solutions with the content of IL ≈0,117 M; ≈0,187 M; ≈0,37 M; ≈0,51 M; ≈0,9 M. First time measuring the longitudinal relaxation T1 of 13C nuclei in [С8mim]Cl  were conducted in the temperature range 25°С - 75°С. According to the obtained relaxation times the molecular mobility of the carbon nuclei can be estimated. The possibility of determining the critical micelle concentration using data from the spin-lattice relaxation of carbon has been shown. The  H/D exchange reaction between heavy water and an ionic liquid H(2) proton was observed at concentration higher than critical micelle concentration. Dependence of exchange on the acidity of the solution were also observed a series of experiments with addition of HCl to the [C8mim]Cl/D2O system.
