Thermodynamics for proton dissociation from aqueous imidazolium ion at temperatures from 278.15 K to 393.15 K and at the pressure 0.35 MPa: apparent molar volumes and apparent molar heat capacities of the protonated and neutral imidazole

Viscosity, Density, and Volatility of Binary Mixtures of Imidazole, 2-Methylimidazole, 2,4,5-Trimethylimidazole, and 1,2,4,5-Tetramethylimidazole with Water

“…Both Enea et al and Jardine et al were concerned with the properties of Im at infinite dilution. In Figure , the data produced in this research are shown against that of Jardine et al Good agreement between both data sets can be observed. Enea et al proposed a linear dependency between molality and apparent volume of Im in aqueous solution at 298 K. Figure includes the apparent molar volumes predicted for Im at 298 K, which fit nicely with the results produced at lower Im concentrations both for this work and for that of Jardine et al…”

“…At higher imidazole concentrations, the assumption that the apparent molar volume of water is constant may fail. Both Enea et al 33 and Jardine et al 34 were concerned with the properties of Im at infinite dilution. In Figure 6, the data produced in this research are shown against that of Jardine et al 34 Good agreement between both data sets can be observed.…”

Enea et al Standard uncertainties are u(T) = 0.05 K, u(P) = 0.3 kPa, u(x 1 ) = 0.003, u(y 1 ) = 0.00001, u(a w ) = 0.01.…”
