Surface tension measurements with validated accuracy for four 1-alkyl-3-methylimidazolium based ionic liquids

Surface tension of 1-alkyl-3-methylimidazolium based ionic liquids with trifluoromethanesulfonate and tetrafluoroborate anion

“…(1) of the present study and for other ionic liquids from similar equations published in Refs. [10,11]. For comparison, the surface tension data reported for the imidazolium based ionic liquids in question by other authors [3,9] are included into Fig.…”

“…As to the dependence on anion, the surface tension increases along the sequence [NTf 2 ] < [CF 3 . Source: Red marks, Freire et al [3]; ⊗, Carvalho et al [9]; black marks, this work and Klomfar et al [10,11]. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)…”

“…Year this and our previous studies [10,11] for 15 ionic liquids with 5 different cations and 5 different anions are analyzed here in the same respect together with the data of the above mentioned authors. The total number of 21 ionic liquids studied, prevents fallacious conclusions that may occur when this number is substantially limited [12].…”

Effect of temperature and composition on the surface tension and thermodynamic properties of binary mixtures of 1-butyl-3-methylimidazolium thiocyanate with alcohols

“…The temperature dependence of the surface tension of fluids is essential for most industrial applications. Recently, intensive research has been done for the popular ILs [9][10][11][12]. An overview of the literature sources for the experimental surface tension data for the ionic liquids of interest was recently given by Klomfar et al [12].…”

Surface tension and 0.1MPa density for members of homologous series of ionic liquids composed of imidazolium-, pyridinium-, and pyrrolidinium-based cations and of cyano-groups containing anions

“…The essential details of the apparatus and the experimental procedure have been described in [32] and [33]. Here we give some additional details on the used experimental procedure, the working equation of the Wilhelmy plate method, and the uncertainty analysis.…”
