“…The tested vegetable oils have the composition given in Table 1 as measured at the laboratory of the supplier of the soybean oil (Expur Slobozia, Romania). These are typical compositions [5], [9], [10], [11] for the tested oils (olive oil and soybean oil). Both vegetable oils are non-refined (crude) oils.…”

. The authors experimentally determined the influence of temperature and shear rate on the dynamic viscosity of two vegetable oils (soybean oil, olive oil). The hydraulic oil ISO VG 46 was used for comparison. The behavior of these two oils was similar to the hydraulic one, for larger shear rates (30 s-1…80 s-1) and for higher temperatures (60ºC…90ºC). For lower shear rate (3 s-1…30 s-1) and lower temperatures (30ºC…50ºC), the dynamic viscosity of the vegetable oils decreases sharper as compared to the hydraulic oil. The authors determined constants in Azian relation and constants in Ostwald de-Waele, Herschel–Bulkley and Carreau models. Based on laboratory data, the authors determined mathematical models for the dependence of dynamic viscosity on temperature and shear rate, for two vegetable oils, as a polynomial relation that could be used with high degree of confidence in predicting the dynamic viscosity in the range of tested parameters. Maps for this relation η = f(  ,T) and maps of the prediction errors were plotted

“…In recent works, in order to express the dependence viscosity -temperature Andrade equation is used in a linear form [10], [12], [13], [14]. Esteban et al [13] recommend the use of Azian equation ( 2), this being more adequate for analysis on large temperature range [15]:…”

Determination of Solubility Parameters of Ionic Liquids and Ionic Liquid/Solvent Mixtures from Intrinsic Viscosity

et al. 2014

View full text Add to dashboard Cite

The total and partial solubility parameters (dispersion, polar and hydrogen-bonding solubility parameters) of ten ionic liquids were determined. Intrinsic viscosity approaches were used that encompassed a one-dimensional method (1D-Method), and two different three-dimensional methods (3D-Method1 and 3D-Method2). The effect of solvent type, the dimethylacetamide (DMA) fraction in the ionic liquid, and dissolution temperature on solubility parameters were also investigated. For all types of effect, both the 1D-Method and 3D-Method2 present the same trend in the total solubility parameter. The partial solubility parameters are influenced by the cation and anion of the ionic liquid. Considering the effect on partial solubility parameters of the solvent type in the ionic liquid, it was observed that in both 3D methods, the dispersion and polar parameters of a 1-ethyl-3-methylimidazolium acetate/solvent (60:40 vol %) mixture tend to increase as the total solubility parameter of the solvent increases.
