High-Pressure Viscosity and Density Measurements of the Ternary System Methylcyclohexane + cis-Decalin + 2,2,4,4,6,8,8-Heptamethylnonane

Abstract: Measurements of the dynamic viscosity and density of a ternary system composed of methylcyclohexane + cis-decahydronaphthalene (cis-decalin) + 2,2,4,4,6,8,8-heptamethylnonane have been performed for 13 different compositions at 7 isotherms in the range 293.15 K to 353.15 K and 6 isobars up to 100 MPa. The viscosity was measured with a falling-body viscometer, except at 0.1 MPa, where a classical capillary viscometer (Ubbelohde) was used. The experimental uncertainty for the measured viscosities is <2%. The den… Show more

“…A comparison of the predicted viscosities using this scheme with the experimental values was carried out, and the resultant deviations are reported in Table 13. Given the kind of viscosity behavior this ternary system develops (see [1][2][3][4]), the obtained mixture results are satisfactory taking into account that they are obtained by a totally predictive method based on pure component properties and in conjunction with a simple cubic EOS. A comparison of the results given in Table 13 for the f-theory with those given in Table 11 shows that the free-volume model gives better results, especially for the maximum deviation.…”

“…These two viscosity mixing laws are totally predictive in the sense that only pure component properties are required. In this work, the viscosity calculations with the Katti-Chaudhri mixing law were performed using the experimental densities reported in [1][2][3][4] in order to obtain the molar volume of the pure compounds and the mixtures. The deviations obtained between the predicted viscosities and the experimental values are given in Table 2 for both mixing laws.…”
