Viscosities and Densities of Dilute Solutions of Glycerol Trioleate + Octane, + p-Xylene, + Toluene, and + Chloroform

Abstract

Dynamic viscosities ( ) and densities ( ) of dilute solutions of glycerol trioleate + chloroform, at 10, 15, 20, 25, and 30 °C, and of glycerol trioleate + octane, + p-xylene, + toluene, at 20, 25, 30, 35, and 40 °C, were measured. The dynamic viscosities and the excess volumes were correlated with the composition and temperature through empirical relations. The standard deviations from the derived viscosity equation were of the same order of magnitude as the experimental uncertainties. The excess volumes (V6) have been derived from the density measurements. Vs values were positive for the glycerol trioleate + chloroform system and negative for the other mixtures over the entire range of mole fractions covered in this study. The departure from the ideal behavior is explained on the basis of specific interactions between the components in these mixtures.

Excess molar volumes and dynamic viscosities for binary mixtures of toluene+n-alkanes (C5–C10) at T=298.15K – Comparison with Prigogine–Flory–Patterson theory

“…The k and c parameters were obtained by measurements on double distilled water and benzene at T = 298.15 K. The obtained parameters are k = 0.010 m 2 AE s À2 and c = 1.095 m 2 . The dynamic viscosity was reproducible to within ±2 AE 10 À3 mPa AE s. The temperature in the cell was regulated to ±0.01 K. The electronic timer can measure time to ±0.01 s. Densities, viscosities, and isobaric thermal expansivity of the pure reagents were in good agreement with values found in the literature [21][22][23], reported in table 1.…”

Viscosity measurements of ortho -xylene, meta -xylene, para -xylene and ethylbenzene

“…The viscosity data of Thorpe and Rodger [14], Serrano et al [21], Exarchos et al [28], and Nissema and Koskenniska [29], which were measured at atmospheric pressure, are represented with AAD of better than 0.8%. …”
