(p, VE, T) Measurements of mixtures (DBE + alcohol) at temperatures from (293.15 to 353.15) K and at pressures up to 140 MPa

This work reports new experimental density data (960 points) for 1-propanol and for binary mixturesof dibutyl ether + 1-propanol, +2-propanol and +1-hexanol over the full composition range (5 composi-tions; 0.15 ≤ dibutyl ether mole fraction x ≤ 0.85), between 293.15 and 353.15 K (every 20 K), and for 15pressures from 0.1 MPa up to 140 MPa (every 10 MPa).An Anton Paar vibrating tube densimeter, calibrated with an uncertainty of ±0.5 kg m−3was usedto perform these measurements. The experimental density data were fitted with a Tait-like equationwith low standard deviations. Excess volumes have been calculated from the experimental data andfitted by the Redlich-Kister equation. In addition, the isobaric thermal expansivity and the isothermalcompressibility have been derived from the Tait-like equation.
