Investigation on the molecular interactions between binary mixtures containing diethyl carbonate in combination with nitrobenzene, chlorobenzene and aniline is presented. Ultrasonic velocity and density values were determined for the individual components as well as binary mixtures of the above benzene derivatives with diethyl carbonate at temperatures (293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K over the entire composition range. Further, adiabatic compressibility and acoustic impedance values were calculated using the experimental results. In addition to these parameters, the excess parameters like excess adiabatic compressibility, excess acoustic impedance and deviation in ultrasonic velocity were also obtained. Based on all these results, molecular interactions among the selected components were discussed.

“…Densities of pure liquids and their binary mixtures were determined using a Rudulph research analytical digital densimeter (DDH-2910 USA). The instrument calibration has been described earlier [8]. The uncertainty in the density measurement was found to be ± 3 x 10 -4 g.cm -3 .…”

“…The Prigogine-Flory-Patterson (PFP) theory was used to correlate the V E results for the studied binary mixtures. The details pertaining to PFP theory and different contributions have been reported earlier [24]. The parameters involved for the pure components are obtained by PFP theory and are represented in Table 5.…”

Excess Volumes, Viscosities and Refractive Index for the Binary Mixtures of Acetophenone, Cyclopentanone, Cyclohexanone and 3-pentanone with Dibutyl Maleate at T = (303.15, 308.15 and 313.15) K

Density, viscosity and refractive index of some binary mixtures of dibutyl maleate with acetophenone, cyclopentanone, cyclohexanone, and 3-pentanone have been measured over the entire composition range at (303.15, 308.15 and 313.15) K and at atmospheric pressure. Excess volume (V E ) and deviation in viscosity () have been estimated from the experimental data of density and viscosity. The results of excess properties are interpreted in terms of molecular interactions. These results were fitted to Redlich-Kister polynomial equation to estimate the binary coefficients and standard errors. Further the values of (V E ) have been analyzed using Prigogine-FloryPatterson (PFP) theory. Refractive index composition data are discussed in the light of various equations suggested by Lorentz-Lorentz, Weiner and Newton. The mixture viscosities have also been correlated using Auslaender and Krishnan-Laddha models.

“…Several researchers [7,8] studied the molecular interactions in binary liquid mixtures containing diethyl carbonate by measuring the values of density and speed of sound. As a part of the experimental investigation of the excess thermodynamic properties of industrially important liquids like diethyl carbonate, here we report the densities, speeds of sound, excess adiabatic compressibility (β E ), excess …”
