Abstract
This study presents new experimental data on the density and viscosity of mixtures containing nonane and 2-alkanols (ranging from 2-propanol to 2-hexanol) at a pressure of 0.1 MPa and temperatures between 293.15 and 323.15 K. Molecular interactions between the components were investigated and found to be weak. Additionally, the predictive capability of the PC-SAFT equation of state was evaluated for density calculations. The binary interaction parameter, assumed constant over the temperature range, was fitted using experimental excess molar volume data at each temperature. The PC-SAFT model accurately predicted the experimental densities of the mixtures. Furthermore, two viscosity models were applied and accurately fitted to the experimental data.
期刊介绍：
The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
