Densities ρ of the ternary system (ethanol + chloroform + benzene) and binaries (ethanol + chloroform) and (chloroform + benzene), have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15) K and pressure 101.33 kPa with an Anton Paar DMA 5000 digital vibrating tube densimeter. Excess molar volumes VE were calculated from these densities data and fitted by the polynomial Redlich–Kister (for binary data) and Nagata and Tamura (for ternary data) equations. Radojković et al. equation was used for the prediction of the VE of ternary data. The obtained results have been explained in terms of different effects between molecules of present species, taking into consideration influence of temperature on them.For the correlation of binary and prediction of ternary VE with cubic equation of state (CEOS), the Peng-Robinson-Stryjek-Vera equation of state (PRSV CEOS) coupled with two different types of independent and temperature dependent mixing rules: (i) the composition dependent (vdW1) and (ii) CEOS with GE equation (CEOS/GE) Twu and co-workers (TCBT) model were used. For the correlation of ternary VE data only Twu and co-workers (TCBT) mixing rules were used.
