On February 13, 2020, Cai, Yingjun; von Solms, Nicolas; Zhang, Suojiang; Thomsen, Kaj published an article.Related Products of 79-07-2 The title of the article was Density, Viscosity, and Conductivity of [VAIM][TFSI] in Mixtures for Lithium-Ion Battery Electrolytes. And the article contained the following:

A novel unsaturated and amide-based ionic liquid, [VAIM][TFSI] (3-(2-amino-2-oxoethyl)-1-vinylimidazolium bis(trifluoromethylsulfonyl)amide), was synthesized using a two-step method. Its structure was confirmed by NMR, and its water content was determined by Karl Fischer titration to be below 0.03 wt %. The d., viscosity, and conductivity of the pure ionic liquid and its binary mixtures with acetonitrile were measured at various temperatures and at ambient pressure. Both the d. and viscosity increase with the mole fraction of the ionic liquid and decrease with decreasing temperature Excess molar volumes and viscosity deviations were calculated from the exptl. results. The elec. conductivities in mixtures with different contents of the ionic liquid were investigated at different temperatures The highest conductivity of binary mixtures is achieved at 0.07 mol fraction, with a value of ∼3.32 S·m-1 at 298.15 K. The conductivity of an electrolyte consisting of acetonitrile, LiTFSI, and the ionic liquid was measured to determine the optimal ionic liquid content. The suggested concentration is 3 wt% ionic liquid in this electrolyte, giving a conductivity of ∼4.11 S·m-1 at 298.15 K. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Related Products of 79-07-2
