Liquid density of oxygenated additive 2-propanol at pressures up to 140 MPa and from 293.15 K to 403.15 K

This work reports new density data (175 points) of 2-propanol at 12 temperatures between 293.15 and 403.15 K (every 10 K), and 15 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 have been derived from the Tait-like equation.

► New density data for 2-propanol are reported. ► The pressure and temperature intervals are 0.1–140 MPa and 293.15–403.15 K. ► 175 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.
