High-pressure densities and derived volumetric properties (excess, apparent, and partial molar volumes) of binary mixtures of {methanol (1)+[BMIM][BF4] (2)}

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

“…In order to determine the volumetric behaviors of {PYR 14 (1)+ MeOH(2)} system, density measurements have been determined as a function of the mole fraction x 1 of ILs for the temperatures : 293. 15 Table 1.…”

“…The study of the viscosity, conductivity, and their interrelations for various compositions of PYR 14 and MeOH offered useful information about the ruling interactions and structure of the medium [23].…”

“…However, in the case of ion transport dominated by the mobility of the solvent molecules, the conductivity Fig. 3 a Plot of lnκ against T -1 for PYR 14 …”

“…Where, A κ is the pre-exponential factor, which is a constant; B κ is the pseudo-activation energy, and T 0 is the ideal vitreous transition temperature, which could be approximated to the glass-transition temperature T g , which is 187.15 K for PYR 14 [3]. In Table 4S are compiled the experimental values of ionic conductivity.…”

“…For instance, Abdulagatov et al have recently reported on the volumetric properties, i.e., excess, apparent, and partial molar volumes of 1-butyl-3-methylimidazolium tetrafluoroborate in methanol [14]. Abareshi et al studied the thermodynamic and transport properties of the mixtures of some ionic liquids with alcohols: 1-butyl-3-methylimidazolium hexafluorophosphate and 1-butyl-3-methylimidazolium tetrafluoroborate with methanol and ethanol at different temperatures, pressures, and compositions [15].…”
