Liquid density of oxygenated additives to bio-fuels: 1-Hexanol at pressures up to 140 MPa and from 293.15 K to 403.15 K

This work reports new density data (180 points) of 1-hexanol at twelve different temperatures between 293.15 and 403.15 K (every 10 K), and fifteen different pressures from 0.1 to 140 MPa (every 10 MPa). An Anton Paar vibrating tube densimeter, calibrated with an uncertainty of ± 0.5 kg m−3 was used to perform these measurements. The experimental density data were fitted with the Tait-like equation with low standard deviations. In addition, the isobaric thermal expansivity and the isothermal compressibility were derived from the Tait-like equation.

► New density data for 1-hexanol are reported. ► The pressure and temperature intervals are 0.1–140 MPa and 293.15–403.15 K. ► 180 measured data points were fitted to a Tait-like equation. ► Experimental data points have been compared to Cibulka's correlation. ► The isobaric expansivity and the isothermal compressibility have been derived.
