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.
