Abstract:
We studied transport properties, i.e., viscosity (η), conductivity (σ), and cation and anion self-diffusion coefficients (Dcation, Danion), for C2mim-ILs, N122.1O2-ILs, and N1224-ILs, where C2mim+ is 1-ethyl-3-methylimidazolium, N122.1O2+ is N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium, and N1224+ is N-butyl-N,N-diethyl-N-methylammonium, composed of perfluorosulfonylamide anions. Ten perfluorosulfonylamide anions, i.e., C0C0 (FSA, FSI), C0C1 (FTA), C1C1 (TFSA, TFSI), C1C2, C2C2 (BETA, BETI), C1C4, C4C4, CTFSA, C3FSA, and TSAC, were used in this work. Walden product and "ionicity" quantity were determined from the transport property data. It became apparent that there was high correlation between the Walden product and the "ionicity" quantity for the ILs. The results of the Walden product and the "ionicity" quantity indicated that by comparison with the N122.1O2-ILs and the N1224-ILs the ion dissociation of the C2mim-ILs was large and hardly changed with the amide anion structures.
