Densities and Excess Molar Volumes of the Binary Mixtures of Cyclopentanone with Chloroalkanes at T = (288.15, 298.15, 308.15, and 318.15) K

Abstract

The experimental densities of binary mixtures of cyclopentanone with 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloromethane, 1,2-dichloroethane, 1,3-dichloropropane, 1,4-dichlorobutane, and 1-chlorobutane have been measured at T = (288.15, 298.15, 308.15, and 318.15) K and atmospheric pressure, over the whole composition range. From these results, excess molar volumes, V E, have been calculated and fitted to the Redlich−Kister polynomial equation. The excess molar volumes are negative for the cyclopentanone + 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloromethane, and 1-chlorobutane systems and positive for the other three systems over almost the whole mole fraction range and temperatures studied. The variation of these properties with composition of the binary mixtures is discussed in terms of molecular interactions between components and structural effects.

Refractive indices and their related properties for several binary mixtures containing cyclic ketones and chloroalkanes

“…As a continuation of our previous research on thermodynamic and optical behavior of linear and cyclic ketone + chloroalkane binary mixtures [1][2][3], this paper presents new refractive index experimental data for eleven binary systems of cyclopentanone + 1,2-dichloroethane, + 1,3-dichloropropane, + 1,4-dichlorobutane, + trichloromethane, + 1,1,1-trichloroethane and cyclohexanone + 1-chlorobutane, + 1,2-dichloroethane, + 1,3-dichloropropane, + 1,4-dichlorobutane, +trichloromethane, and +1,1,1-trichloroethane, at T = 298.15 K and atmospheric pressure, over the entire mole fraction range.…”

“…For our cyclopentanone or cyclohexanone + chloroalkane binary mixtures, the molar refraction, R, was evaluated by means of Eq. (6) using the calculated refractive indices with Redlich-Kister parameters (from Tables 5 and 6) and calculated molar volumes (from the Redlich-Kister equation using the parameters published in [2,3]). …”

“…The density measurements of the pure solvents and of the mixtures previously reported [2,3] were performed by means of an Anton Paar DMA 4500 densimeter with a precision of ± 0.05 kg·m − 3 . The DMA cell was calibrated with dry air and ultra pure water at atmospheric pressure.…”

“…In the present paper, from the experimental density data and the excess molar volume, V E , and the molar volumes of pure compounds, V 1 ⁎ and V 2 ⁎ taken from [2,3], the partial molar volumes at infinite dilution, were calculated. The partial properties at infinite dilution are of interest since at the limit of infinite dilution, the solute-solute interaction disappears and only the solute-solvent interactions are present.…”

Excess Heat Capacities of Binary Mixtures Containing o-Chlorotoluene and Pyridine or Isomeric Picolines or Aromatic Hydrocarbons

“…Thermodynamic properties like excess molar volumes, V E , excess molar enthalpies, H E , excess isentropic compressibilities, j E S , and excess Gibbs energy, G E , of liquid mixtures have been successfully utilized to obtain information about molecular interactions and geometrical effects in the mixtures [1][2][3][4][5][6][7]. Heat capacities, C P , and excess heat capacities, C E P À Á 12 , data of liquid mixtures are also related to the structure of the constituent molecules.…”
