Excess Molar Volumes and Excess Logarithm Viscosities for Binary Mixtures of the Ionic Liquid 1-Butyl-3-methylimidazolium Hexaflurophosphate with Some Organic Compounds

Volumetric and transport properties of N-Butyl-N-methylpyrrolidinium bis(Trifluoromethanesulfonyl)imide–methanol binary mixtures

“…The viscosity variations of PYR 14 -MeOH exhibit unusual behavior similar only to a few cases reported in the literature [30,31]. Effectively, at 293.15 K, the viscosity of the pure IL falls by 56% when 21 mol % of methanol is added and for the mixture it increases with x 1 .…”

Densities and excess volumes of binary mixtures of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate with aromatic compound at T=(298.15 to 313.15)K

“…The densities of pure compounds and mixtures were measured by means of an Anton Paar DMA 4500 vibrating-tube densitometer with estimated accuracy of ±0.05 kg AE m À3 . In order to check the purity of the substances, their density were determined at T = 298.15 K and compared with the literature values [33][34][35]. As listed in table 1, the agreement is good.…”

“…Rogers and coworkers [41] reported the formation of liquid clathrates with various ratios in (ionic liquid + aromatic mixtures). Wang and co-workers [35] suggested that quasi-clathrates were probably formed in the mixtures of {[bmim][P-F6] + organic compounds} to include acetone, 2-butanone, 3-pentanone, ethyl acetate, and cyclopentanone. They addressed the issue that at least an unusual structure appeared in the vicinity of this particular composition of the mixtures (x = 0.3) [35].…”

Corrosion of carbon steel in the [P 14666 ][Br] ionic liquid: The effects of γ-radiation and cover gas

“…In our studies on the effect of γ-radiation on the chemical and physical properties of ILs in contact with water or gas [7,19] we have observed formation of micelles and enhancement of light scattering and attributed these phenomena due to agglomeration of the IL molecules facilitated by the radiolytically-produced small organic molecules at very small concentrations. The increase in transport of molecular oxidant, in particular H2O in the hygroscopic IL, will increase the rate of interfacial transfer of H2O from the gas phase to the IL phase and accelerate their diffusion into the IL [42]. The SEM images and Raman spectra of carbon steel surfaces corroded for 96 h in hexane-IL exposed to different cover gases are compared in Figure 9.…”
