(r, VE, T) Measurements of the Ternary Mixture (Dibutyl Ether + 1-Heptanol + Heptane) at Temperatures up to 393.15 K and Pressures up to 140 MPa and Modeling Using the Peng-Robinson and PC-SAFT Equations of State

New measurement density data (1360 points) for dibutyl ether (1) + 1-heptanol (2) + heptane (3), were measured at various temperatures T (298.15 to 393.15) K and at various pressures p (0.1 to 140) MPa, adopting an Anton-Paar Densimeter (DMA HPM). The excess molar volumes VE of the studied ternary system were derived from the measured density data. Subsequently, they are calculated with the Singh and Redlich-Kister equations. VE values were employed to write the different interactions imply in the mixture. The Peng-Robinson and the PC-SAFT equations of states (EoS) were performed for their potential to correlate and predict experimental density for ternary mixture. The PC-SAFT parameters of pure compounds that constituted the studied ternary mixture were regressed by using the measured data of density of each pure compounds.
