Data and QSPR study for viscosity of imidazolium-based ionic liquids

A group contribution method to estimate the viscosity of ionic liquids at different temperatures

“…Also in Table 1, shows another comparison between the proposed GCM, and some QSPR models available in the literature for the estimation of the viscosity of ILs [20][21][22][23][24][25][26][27]. As observed in this table, all QSPR models are applied only to specific ionic liquids and they present a correlation with an R 2 of 0.8 to 0.94.…”

“…However, to the best of the author's knowledge, there is no application for the estimation of the liquid viscosity that includes a heterogeneous set of ILs, such as the one presented here using a simple GCM. Table 1 lists selected applications to estimate viscosity [9,10,[18][19][20][21][22][23][24][25][26][27]. In this work, viscosity of several ILs at different temperatures have been correlated and estimated using an accurate GCM with structural 6groups for the cation-anion parts.…”

A quantitative prediction of the viscosity of ionic liquids using Sσ-profilemolecular descriptors

“…Tel./Fax: +86 01062558174 E-mail address: xpzhang@ipe.ac.cn, sjzhang@ipe.ac.cn 3 for some systems. In Han's study 34 , the CODESSA software was used to build four QSPR models, but the established models have some disadvantages. Firstly, only a small amount of data of imidazolium-based ILs was used to build the model.…”

Anodic behavior of Mg in acidic AlCl3–1-ethyl-3-methyl-imidazolium chloride ionic liquid

“…The viscosity of imidazolium-based ionic liquid is strongly dependent on the cation-anion interaction, molecular structure, hydrogen bonds et al of the ionic liquid [24,26]. The high viscosity of Mg dissolved ionic liquid might be caused by the intense cation-anion electrostatic interaction in the Mg dissolved ionic liquid, which might be of a complex structure comprised of Mg(AlCl 4 ) 3 À , Al 2 Cl 7 À and EMI + .…”
