Pinto, Camila N. published the artcileViscosities and Densities of Fatty Alcohol Mixtures from 298.15 to 338.15 K: Estimation by Kay’s Rule and Prediction by the UNIFAC-VISCO and GC-UNIMOD Group Contribution Methods, Safety of n-Octanol, the main research area is viscosity density fatty alc mixture Kay; UNIFAC VISCO UNIMOD group.
The phys. properties d. and viscosity of 21 binary mixtures composed of 1-hexanol, 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, 1-undecanol, and 1-dodecanol were determined at temperatures from 298.15 to 338.15 K, stepped by 10 K. Well-known methods, based on the phys. properties of the pure compounds and their compositions in the mixtures, were used to estimate d. (simple form of Kay’s rule) and viscosity (logarithmic form of Kay’s rule). For d. values, the absolute average deviations (AADs) were no higher than 0.06%, when mass fraction was used as the unit of concentration The viscosity calculations resulted in overall AADs from 1.77% (using molar fraction as the unit of concentration) to 1.85% (using mass fraction as the unit of concentration). Addnl., the predictive capability of the UNIFAC-VISCO and GC-UNIMOD models was tested for viscosity. Satisfactory results were found for all the sets of parameters evaluated in the prediction, with AAD values less than 2%, indicating the appropriate application of these models.
