    Viscosity and density of binary mixtures of cyclohexane with n-octane, n-dodecane, and n-hexadecane under high pressures (1991)
    Springer
    International journal of thermophysics 12 (1991), S. 245-264

    ISSN: 1572-9567
    Keywords: alkanes ; cyclohexane ; density ; dodecane ; hexadecane ; mixtures ; octane ; Tait equation ; viscometer ; viscosity

    Topics: Physics
    Notes: Abstract The viscosity and density of three binary mixtures of cyclohexane with n-octane, n-dodecane, and n-hexadecane have been measured at 298, 323, and 348 K at pressures up to 150 MPa or freezing pressures. The measurements of the viscosity were performed by a torsionally vibrating crystal viscometer on a relative basis using benzene and cyclohexane as reference materials. The density was measured using a high-pressure burette apparatus. The uncertainties of the measurements are estimated to be less than 2% for viscosity and 0.1% for density, respectively. The effects of temperature, pressure, density, and composition on the viscosity are discussed. Applicabilities of several empirical correlating equations to the viscosity data were examined.

    Density and viscosity of linear perfluoropolyethers under high pressures (1989)
    Springer
    International journal of thermophysics 10 (1989), S. 857-870 
    Details
    ISSN: 1572-9567
    Keywords: compressibility ; density ; fluorocarbon oil ; free-volume equation ; high pressure ; perfluoropolyether ; specific volume ; Tait equation ; viscosity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract New experimental data on the density and viscosity of linear, unbranched perfluoropolyethers are presented at temperatures from 273 to 333 K and pressures up to 180 MPa. The measurements were carried out by a high-pressure burrette apparatus and a falling-cylinder viscometer. The uncertainties of the measurements are estimated to be less than 0.09% for the specific volume and 2.5% for the viscosity. The P-V data at each temperature are correlated satisfactorily by the Tait equation. The viscosity data are also analyzed and correlated with pressure or molar volume by several empirical and theoretical equations.

    Volumetric properties of mixtures of 1,4-dioxane and water at high pressures (1996)
    Springer
    International journal of thermophysics 17 (1996), S. 441-454 
    Details
    ISSN: 1572-9567
    Keywords: aqueous solutions ; compressibility ; density ; dioxane ; high pressure ; partial molar volume
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Densities of aqueous of 1,4-dioxane have been measured at temperatures from 298 to 348 K and at pressures up to 40 MPa by a vibrating-tube method. Molar volumes obtained with an estimated uncertainty of ±0.2°,% are correlated with pressure by the Tait equation within the experimental uncertainty. Pressure and composition dependences of the excess molar volume, partial molar volume, and isothermal compressibility are determined and they are compared with those of other aqueous solutions.

    Thermal conductivity and density of toluene in the temperature range 273–373 K at pressures up to 250 MPa (1982)
    Springer
    International journal of thermophysics 3 (1982), S. 201-215 
    Details
    ISSN: 1572-9567
    Keywords: density ; isothermal compressibility ; Tait equation ; thermal conductivity ; thermal expansion coefficient ; toluene ; transient hot-wire method
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract New experimental data on the thermal conductivity and the density of liquid toluene are presented in the temperature range 0–100°C at pressures up to 250 MPa. The measurements of thermal conductivity were performed with a transient hot-wire apparatus on an absolute basis with an inaccuracy less than 1.0%. The density was measured with a high-pressure burette method with an uncertainty within 0.1%. The experimental results for both properties are represented satisfactorily by the Tait-type equations, as well as empirical polynomials, covering the entire ranges of temperature and pressure. Furthermore, it is found that simple relations exist between the temperature dependence of thermal conductivity and the thermal expansion coefficient, and also between the pressure dependence of thermal conductivity and the isothermal compressibility, as are suggested theoretically.

    Volumetric properties of mixtures of fluoroalcohols and water at high pressures (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 245-259

    ISSN: 1572-9567
    Keywords: aqueous solutions ; compressibility ; density ; nuoroalcohols ; high pressure ; hydrocarbon alcohols ; Raman spectroscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Densities of aqueous solutions of 2,2,2-trifluoroethanol, 2,2,3,3-tetranuoropropanol, and 2,2,3,3,3-pentanuoropropanol have been measured with a vibrating-tube densitometer. Measurements were performed at temperatures of 298 and 323 K and at pressures up to 80 MPa with an estimated uncertainty of ±0.2 %. Molar volumes obtained for these mixtures are correlated with pressure by the Tait equation within the experimental uncertainty. Excess molar volume, isothermal compressibility, and partial molar volume of these mixtures are determined in terms of this correlation equation and compared with those of the aqueous solutions of hydrocarbon alcohols. Composition dependence of partial molar volume is discussed in comparison with that of Raman spectroscopic data.
