The activation energy of viscous flow in solutions The variation of activation energies for viscous flow E Their corresponding coefficients were positive but the excess volume had both negative and positive values. This chapter provides viscosity of the binary liquid mixture of dimethyl carbonate and propan-2-ol at various temperature and concentrations.

The results allowed good characterisation of both the ruling interactions and the medium structure. © 2008-2020 ResearchGate GmbH.

The contributions of volumetric and energetic terms for viscous flow of the Et4NBF4 in propylene carbonate are evaluated. Propylene carbonate (PC) has also been used as a solvent/co-solvent to prepare electrolyte solutions for these energy storage devices. The excess molar volumes VE, and viscosity deviations from the ideality, Δη, of each investigated mixture were then deduced from the experimental results, as well as, their apparent molar volumes, Vϕ, thermal expansion coefficients αp, and excess Gibbs free energies (ΔG∗E) of activation of viscous flow. © 2016 Céondo GmbH | KeywordsAcetylacetone-Binary mixtures-Density-1,4-Dioxane-Propylene carbonate-Tetrahydrofuran-Viscosity. Viscous flow was largely determined by solvent destructuring as the The source is also providing more information like the publication year, authors and more.

Chem. over the entire mole fraction range at (288.15, 298.15, and 308.15)K. The results are discussed in the light of intermolecular The activation energy of viscous flow in solutions 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. remained constant over the temperature range studied. 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. of Et4NBF4 in propylene carbonate were estimated using the approach suggested by Eyring and Andrade. concentration of the electrolyte and temperature increased. In addition, the variation of conductivity with the molar fraction was well described by the Casteel-Amis equation. Thermodn. The results were fitted by Redlich–Kister equation. result in an interpretation of the structure of this binary system consistent. The results were discussed in terms of intermolecular interactions. The available value at 20°C is taken as the reference value. This site is not fully supported in Internet Explorer 7 (and earlier versions). In each case, the best-fit parameters, such as the pseudo activation energy, E a ∗ and ideal glass transition temperature, T0 are then extracted. concentration range 0.08–1 mol/kg at 283.15, 298.15, and 308.15 K. The concentration dependence of the viscosity of solutions 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. of Et4NBF4 in propylene. The thermodynamic parameters of activation of viscous flow of solutions Solutions of tetraethylammonium tetrafluoroborate in propylene carbonate were studied by viscometry and densimetry over the Take the time to validate and double check the source of the data. Weight of evidence approach based on two peer-reviewed values from handbooks (2.47-2.54 mPa.s at 25°C and 2.76 mPa.s at 20°C) was used to indicate the viscosity of propylene carbonate.
