Experimental Measurements and Modeling of Density and Viscosity for Methyl Caprate+1-Alkanol at Atmospheric Pressure and Different Temperatures

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.
