Densities and dynamic viscosities of ionic liquids having 1-butyl-3-methylimidazolium cation with different anions and bis (trifluoromethylsulfonyl)imide anion with different cations in the temperature range (283.15 to 363.15) K

Viscosity and Density of Two 1-Alkyl-3-methyl-imidazolium Triflate Ionic Liquids at High Pressures: Experimental Measurements and the Effect of Alkyl Chain Length

“…However, it can be seen that the majority of the deviations from our results lie within an interval of ±5%. We note that this limit may be considered not too high, taking into account the difficulties usually associated with the measurement of the viscosity of ionic liquids. , In particular, it is to be marked that the results obtained by Tokuda et al, Yadav et al, Anwar et al, Fatima et al, and Mbondo Tsamba et al deviate less than about ±3%, which is commensurate with the uncertainty of the present measurements.…”

Viscosity of 1-Alkyl-1-methylpyrrolidinium Bis(trifluoromethylsulfonyl)imide Ionic Liquids Saturated with Compressed CO2

“…Many research groups have measured the viscosities of pure ionic liquids at various temperatures and pressures. Recently, Yadav et al measured the viscosity of a series of ionic liquids to assess the influence of the natures of the cation and the anion over the temperature range from 283.15 to 363.15 K. 24 Ahosseini and Scurto measured the effect of pressure on the viscosities of pure 1-alkyl-3-methylimidazolium-based ionic liquids with various alkyl chain lengths and anions up to 126 MPa at a temperature of 343.15 K using an oscillating-piston viscometer. 25 In one of the first investigations of the viscosity of IL/CO 2 mixtures, Lu 1-butyl-3-methylimidazolium hexafluorophosphate [BMIm]-[PF 6 ] with CO 2 mixtures using a spectroscopic probe.…”

Densities, Viscosities, and Refractive Indices of Binary Room-Temperature Ionic Liquids with Common Cations/Anions

“…The densities, viscosities, and refractive indices of the seven binary RTIL systems were measured in the temperature range of 283.15 to 353.15 K at intervals of 5 K. The numerical data of density (Tables S1–S7), viscosity (Tables S8–S14), and refractive index (Tables S15–S21) are given in the Supporting Information. Of course, water content of binary RTIL is important information gained by Karl–Fischer titration (less than 100 ppm). − Alternatively, we dried binary RTIL samples before each measurement and confirmed the absence of water and any impurities (other peaks) by 1 H NMR measurements.…”
