Density and Refractive Index for Binary Systems of the Ionic Liquid [Bmim][BF4] with Methanol, 1,3-Dichloropropane, and Dimethyl Carbonate

Excess properties for binary systems ionic liquid+ethanol: Experimental results and theoretical description using the ERAS model

“…The uncertainty of the measurement is estimated to be ± 1 × 10 −4 g cm −3 . Further experimental details can be found elsewhere [39]. Isobaric molar heat capacities, C p , were obtained from experimental density and isobaric heat capacity per unit volume, C p V −1 .…”

Density and refractive index in mixtures of ionic liquids and organic solvents: Correlations and predictions

“…Almost all available methods for this purpose require the knowledge of the actual viscosity of the sample and use a simple analytical expression to correct it [16][17][18]. The main advantage of the DMA5000 densimeter is its ability to apply such a correction automatically without the need for any information about the viscosity of the sample [13,39]. The instrument was calibrated with ultrapure water and dry air.…”

Micelle formation of nonionic surfactants in a room temperature ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate: Surfactant chain length dependence of the critical micelle concentration

“…A lot of data are available in literature for these physical quantities of bmimBF 4 . Instead of viscosity and refractive index of the surfactant solution, we used those of pure bmimBF 4 ; i.e., g = 102.8 at 25°C and 79.9 at 30°C (average of reported values [21][22][23][24][25][26]) and n = 1.422 (average of reported values [27][28][29][30][31]). The values of mean hydrodynamic diameter reported in this paper are based on the volume weighted size distribution.…”
