Density, ρ, viscosity, η, and conductivity, σ, measurements of binary mixtures containing the pyrrolidinium nitrate Protic Ionic Liquid (PIL) and propylene carbonate (PC), are determined at the atmospheric pressure as a function of the temperature from (283.15 to 353.15) K and within the whole composition range. Their corresponding coefficients were positive but the excess volume had both negative and positive values. Densities and viscosities of the binary mixtures of propylene carbonate with benzene, 1,4-dimethylbenzene and ethylbenzene were measured over the entire mole fraction range at 288.15, 298.15 and 308.15 K. Using the experimental values of densities and viscosities the excess molar volumes and viscosity deviations were calculated. Generation of bulky cyclic carbonates such as octylene carbonate (OcC) and do-decylene carbonate (DoC) leads to an increase of the viscosity in the reaction mixture, yields are only 80 percent for OcC and 65 percent for DoC. a,η carbonate were estimated using the approach suggested by Eyring and Andrade. According to the Walden rule, the ionicity of each mixture was then evaluated as a function of the temperature from (283.15 to 353.15) K and of the composition. concentration of the electrolyte and temperature increased.

Crude oil viscosity as function of gravity - Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F; Dynamic or Absolute Viscosity Converting Chart - Dynamic viscosity converting chart with units like Poiseuille - Poise - centiPoise and more The concn. Thermodyn. Pires, J., Timperman, L., Jacquemin, J., Balducci, A., Anouti, M.: J. Chem. The temperature dependence of both the viscosity and conductivity of each mixture exhibits a non-Arrhenius behaviour, but is correctly fitted by using the Vogel–Tamman–Fulcher (VTF) equation. The source is also providing more information like the publication year, authors and more. The conductivity-temperature relationship was found to have a better fitting on the Vogel-Tammann-Fulcher model than on the Arrhenius law.
