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