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

Influence of the anion on the surface tension of 1-ethyl-3-methylimidazolium-based ionic liquids

“…Positive and negative relative deviations are found between our data and those already published. However, a close agreement between our data and those recently published by Pátek and co-workers was found [31,33]. It should be stressed that the authors employed both the du Noüy ring and Wilhelmy plate methods to confirm the accuracy of the measurements [31,33].…”

Although some large deviations exist between our data and literature data it must be noted that large deviations are still observed among the data from differ- [28,34].…”

“…The percentage relative deviations (%RD) between our data and those from literature [28][29][30][31][32][33][34][35] are summarized in figure 3. Positive and negative relative deviations are found between our data and those already published.…”

Effect of temperature on the physical properties of 1-butyl-3-methylimidazolium based ionic liquids with thiocyanate and tetrafluoroborate anions, and 1-hexyl-3-methylimidazolium with tetrafluoroborate and hexafluorophosphate anions

“…Although some physical properties of the ILs of this work are available in literature [5][6][7][8][9][10][11][12][13][14][15][16][17], but due to the insufficient data within all ranges of temperatures and lack of experimental values of kinematic viscosity, our effort was focused on five properties including density, refractive index, surface tension, dynamic and kinematic viscosities of 4 ILs, 1-butyl-3-methylimidazolium thiocyanate ( 6 ] had a certified purity greater than 0.98, 0.99, 0.99, and 0.99 mass fraction, respectively. Table 1 contains the purities and suppliers of materials used in this work.…”
