Experimental density and PC-SAFT modeling of biofuel mixtures (DBE + 1-Heptanol (cas 111-70-6)) at temperatures from (298.15 to 393.15) K and at pressures up to 140 MPa

This work reports new experimental density data (816 points) for binary mixtures of dibutyl ether (DBE) + 1-heptanol over the composition range (5 compositions; 0.15 ≤ dibutyl ether mole fraction x ≤ 0.85), between 298.15 and 393.15 K, and for 23 pressures from 0.1 MPa up to 140 MPa. An Anton Paar vibrating tube densimeter, calibrated with an uncertainty of ±0.7 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. In addition, the isobaric thermal expansivity and the isothermal compressibility have been derived from the Tait-like equation, provided as supplementary material.In addition, PC-SAFT parameters of DBE and 1-heptanol were optimized using density data at atmospheric pressure. From PC-SAFT, density of mixture was reasonably well predicted with an average relative deviation varied between 0.00015% and 2.80%.
