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

• We report new density data for dibutyl ether + 1-propanol, 2-propanol and 1-hexanol.
• The pressure and temperature intervals are 0.1–140 MPa and 293.15–353.15 K.
• 960 data points measured at 5 compositions were fitted to a Tait-like equation.
• Excess volumes have been calculated from the experimental data.
• The isobaric expansivity and the isothermal compressibility have been derived.

This work reports new experimental density data (960 points) for 1-propanol and for binary mixtures of dibutyl ether + 1-propanol, +2-propanol and +1-hexanol over the full composition range (5 compositions; 0.15 ≤ dibutyl ether mole fraction x ≤ 0.85), between 293.15 and 353.15 K (every 20 K), and for 15 pressures 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−3 was used to perform these measurements. The experimental density data were fitted with a Tait-like equation with low standard deviations. Excess volumes have been calculated from the experimental data and fitted by the Redlich–Kister equation. In addition, the isobaric thermal expansivity and the isothermal compressibility have been derived from the Tait-like equation.
