Viscosity and density of liquid mixtures ofn-alkanes with squalane

Abstract

Viscosity and density measurements are reported for binary liquid mixtures of n-butane and n-hexane with squalane in the temperature range from 273 to 333 K. The viscosity measurements have been carried out by using a capillary viscometer calibrated with standard liquids, that is. JS5. JS10, JS20, and water. The uncertainty in the viscosity data was estimated to be _+ 1.7 %. The density needed for the calculation of the viscosity has been measured by using a glass pycnometer within an accuracy of +0.04%. In the prediction of the viscosity, the scheme of Assael et al. fails for mixtures of this type differing greatly in size.

Measurements of the Liquid Viscosities of Mixtures of n-Butane, n-Hexane, and n-Octane with Squalane to 30 MPa

“…The present viscosity data for mixtures of n-butane and n-hexane with squalane at 0.1 MPa agree with previous results [2] within 3.0% independent of the different experimental techniques. The present viscosity data at temperatures between 298 and 333 K, and up to 30 MPa agreed with literature data for n-hexane [7][8][9] and n-butane [7,11,12] to within 1.7%, and 3.8%, respectively.…”

“…In previous papers [1,2], we have reported viscosity data for mixtures of n-butane, n-hexane, and n-octane with squalane, which represented model mixtures of refrigerants with refrigeration oil, using a capillary viscometer at temperatures ranging from 273.15 to 333.15 K at the saturated vapor pressure. The present paper extends the viscosity measurements on mixtures of n-butane, n-hexane, and n-octane with squalane to higher pressures, up to 30 MPa.…”

Viscosity Measurements and Correlation of the Squalane + CO2 Mixture

“…In our previous study, we measured the viscosity of squalane + hydrocarbon [1,2] and glycol + HFC-134a [3] systems. The present paper describes continuing work on the experimental determination of the viscosity of liquid mixtures consisting of a lubricating oil and refrigerants.…”

Excess Volumes, Densities, Speeds of Sound, and Viscosities for the Binary Systems of 1-Octanol with Hexadecane and Squalane at (298.15, 303.15 and 308.15) K

“…As far as we know, there are not any literature data available for the studied binary mixtures at these temperatures. A literature review shows that the thermodynamic properties of binary mixtures containing alcohols with either C 16 H 34 or C 30 H 62 are not well known [1][2][3][4][5], whereas those for binary mixtures of hydrocarbons with C 16 H 34 or C 30 H 62 are available in the literature [6][7][8][9][10][11][12][13][14][15][16][17][18]. So it offers us a good opportunity to study the mixing behavior in such systems.…”
