Densities (ρ) are reported for the 2-methoxyethanol (component l)/water (component 2) solvent system, over the full composition range (0 ≤ X1 ≤ 1) at temperatures (t) from -10 to +80�C. The experimental data have been fitted by three empirical relations that represent the functions ρ = ρ(t), ρ = ρ(X1), ρ = p(t,X1), and the excess volume values by a Redlich-Kister equation. The 1:2 2-methoxyethanol/water adduct appears to be stable throughout the temperature range.

Excess molar volumes (VEm) and dynamic viscosities (η) for five (alkoxyethanol + propylamine) mixtures have been measured as a function of composition at 298.15 K and atmospheric pressure. The alkoxyethanols were 2-methoxyethanol, 2-(2-methoxyethoxy)ethanol, 2-(2-ethoxyethoxy)ethanol, 2-(2-butoxyethoxy)ethanol, and 2-{2-(2-methoxyethoxy)ethoxy}ethanol. The excess molar volumes VEm are all negative over the whole composition range. The viscosity data have been correlated by the methods of Kendall and Monroe, Grunberg and Nissan, Tamura and Kurata, Hind, Katti and Chaudry, and with McAllister correlations. From the experimental data, deviations in the viscosity (Δη) have been calculated. The results are discussed in terms of the interaction between components.Key words: excess volume, viscosity, binary mixtures.

Excess molar volumes (VmE) and dynamic viscosities (η) have been measured as a function of composition for binary liquid mixtures of propylamine with 2,5-dioxahexane, 2,5,8-trioxanonane, 2,5,8,11-tetraoxadodecane, 3,6,9-trioxaundecane, and 5,8,11-trioxapentadecane at 298.15 K. The excess volumes are positive over the entire range of composition for the systems propylamine + 2,5-dioxahexane, and + 3,6,9-trioxaundecane, negative for the systems propylamine + 2,5,8,11-tetraoxadodecane, and + 5,8,11-trioxapentadecane, and change sign from positive to negative for the remaining system propylamine + 2,5,8-trioxanonane. From the experimental data, deviations in the viscosity (Δln η) and excess energies of activation for viscous flow (ΔG*E) have been derived. These values are positive for all mixtures with the exception of propylamine + 2,5-dioxahexane.Key words : excess volume, viscosity, binary mixtures.

Kister Equation

Densities for binary mixtures of cyclopentane with 1-propanol, 1-pentanol, and 1-heptanol over the whole composition range have been measured at temperature 318.15 K. From these densities, excess molar volumes were calculated. All the experimental excess molar volumes were fitted to Redlich–Kister equation and were analyzed with the help of Prigogine–Flory–Patterson theory. Also isobaric expansibilities and their excess counterparts were calculated. Further different approaches were analysed for calculating ideal expansibilities.

Densities and excess molar volumes, VE, of heptane-1-chloropropane, heptane- 1-chlorobutane, heptane-1-chloropentane, and heptane-1-chlorohexane systems are reported at 298.15 K and atmospheric pressure over the whole composition range. Value of VE was found to be slightly negative at lower mole fractions and slightly positive at higher mole fractions in case of the heptane-1-chlorohexane system. For all the other systems, VE was positive. The VE results were correlated using the fourth-order Redlich-Kister equation, the maximum likelihood procedure being applied for evaluating the adjustable parameters.

Good Agreement

Excess molar volumes, VE, have been measured for binary liquid mixtures of dimethyl sulfoxide (DMSO) with xylenes (o- xylene, m- xylene and p-xylene) at 298.15 K and atmospheric pressure. The excess volumes values were found negative over the entire composition range for all the mixtures. The VE values increase in order: p-xylene[ m-xylene[ o-xylene. The Flory and Prigogine-Flory-Patterson (PFP) thermodynamic theories of solution have been used to analyze the VE data. The calculated VE values were found to be in good agreement with the experimental data.

The excess molar volumes, [Formula: see text], of 2-hexanone (MBK) with n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, n-dodecane, and n-tridecane have been obtained at 298.15 K from densities measured with a vibrating tube densimeter. The [Formula: see text] are positive over the entire composition range in all mixtures, with the exception of the MBK + n-hexane system, where an inversion of the sign of [Formula: see text] is observed. In other systems, [Formula: see text] increases with increasing size of the alkyl group in n-alkane.

Molar Volumes

Excess molar volumes VEm at 298.15 K and atmospheric pressure were calculated over the entire composition range from densities measured with a vibrating-tube digital densimeter for the binary mixtures butyl acetate + methanol, + ethanol, + propan-1-ol, + butan-1-ol, + pentan-1- ol, + hexan-1-ol, + heptan-1-ol, + octan-1-ol, + nonan-1-ol and + decan-1-ol. The excess volumes are positive over the entire composition range for these mixtures except the system butyl acetate + methanol, for which all VEm values are negative. The excess volumes show a consistent trend towards more positive values as the length of the hydrocarbon chain of the alkanol increases. The results suggest the presence of specific interactions.

Excess molar volumes (VEm) and viscosities (η) for mixtures of triethylene glycol dimethyl ether + dichloromethane, + trichloromethane, and + tetrachloromethane have been determined at 298.15 K and atmospheric pressure over the whole concentration range. From the experimental results, deviations in viscosities (Δ ln η) have been calculated. These properties were fitted to the polynomial relations to obtain the coefficients and the standard deviations. The results have been analysed in terms of molecular interactions between components.Key words: experiments, data, excess volume, viscosity deviation, binary mixtures.

This research article reports the experimental results of the density, viscosity, refractive index, and speed of sound analysis of binary mixtures of dimethylsulfoxide (DMSO) + 1-phenylethanone (acetophenone) and + 1,4-dimethylbenzene (para-xylene) over the whole composition range at 313.15, 318.15, 323.15, and 328.15 K and at atmospheric pressure. The excess molar volumes (VE), viscosity deviations (Δη), excess Gibbs energy of activation (GE), deviations in isentropic compressibility (KSE), deviations in speed of sound (uE), and deviations in the molar refraction (ΔR) were calculated from the experimental data. The computed quantities were fitted to the Redlich-Kister equation to derive the coefficients and estimate the standard error values. The viscosities have also been correlated with two, and three-parameter models, that is, Heric correlation, McAllister model, and Grunberg-Nissan correlation, respectively.
