Abstract
This study provides new experimental data for the density and viscosity of mixtures containing methyl caprate and 1-alkanol (1-propanol to 1-hexanol) at 0.1 MPa and different temperatures (293.15 K to 323.15 K). We analyzed the molecular interactions between the components and found that are weak. The PC-SAFT equation of state accurately modeled the density of the mixtures without fitted parameters. This equation of state considered hydrogen bonding between methyl caprate and 1-alkanol. Moreover, two correlations for viscosity were successfully applied to fit the experimental viscosity data with good accuracy.
期刊介绍：
International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
