“…The deviations in isentropic compressibility, Dj s , were calculated using equation (3): The interactions between the binary mixtures lead to the decrease in the free-space, thereby contributing to the negative deviation in isentropic compressibility [38]. The deviation in isentropic compressibility, Dj s , over the entire composition range of [BMIM] + [SCN] À for both systems is plotted in figure 5.…”

“…On mixing, ethyl acetoacetate being more polar will induce a dipole moment in the ketone molecule, which might lead to a weak dipole-induced dipole interaction between the component molecules. Negative deviation in viscosities, η E , was also being observed due to the differences in molecular size of component molecules [16][17][18] as in the present binary mixtures. The magnitude of negative values of excess viscosities, η E ( Fig.…”

Kinematic viscosities (ν) of binary mixtures of ethyl acetoacetate (EAA) + aliphatic ketones (C4-C9) have been determined as a function of composition at 298.15 K. The dynamic viscosity (η), excess viscosity and excess Gibbs free energy of activation for viscous flow, (∆G *E) were also calculated. Excess viscosities (η E) and excess Gibbs free energies of activation for viscous flow (∆G *E) were calculated from the experimental viscosity data and were fitted to a Redlich-Kister type polynomial. The excess viscosity shows negative deviations over the entire range of solvents composition for the mixtures of (ethyl acetoacetate) + butan-2-one, hexan-2-one, heptan-2-one, octan-2one and nonan-2-one and a positive deviation for the binary mixtures of ethyl acetoacetate + pentan-2-one system. The (∆G *E) were all positive over the entire range solvents composition for the binary mixtures. The experimental results were used to test some semiempirical equations to correlate viscosity-composition data.

“…This fact is well known as the transport phenomenon and thermo-physical properties of mixed solvents. The present study is a continuation of our earlier research [1][2][3][4] on thermodynamic properties of binary liquid mixtures. The liquids were chosen in the present investigation on the basis of their industrial importance.…”

Measurement of densities q, viscosities g, and ultrasonic speeds u has been carried out for binary mixtures of N,N-diethylaniline (N,N-DEA) with acetophenone, cyclopentanone, cyclohexanone (CH), and 2-methylcyclohexanone (Me-CH) and their pure liquids at (303.15 and 308.15) K. These experimental data have been used to calculate the excess molar volume V E , deviation in ultrasonic velocity Du, deviation in isentropic compressibility Dj s , and deviation in viscosity Dg. The variation of these properties with composition of the mixtures suggests dipole-dipole interactions and charge-transfer complex formation between N,N-diethylaniline and dipolar ketones. The magnitude of the property is found to depend on the chain length of the ketones' molecule. The viscosity data have been correlated using three equations: Grunberg and Nissan (Nature 164:799-800, 1949), Katti and Chaudhri (J Chem Eng Data 9:442-443, 1964), and Hind et al. (Trans Faraday Soc 56:328-330, 1960). These results have been fitted to the Redlich-Kister polynomial using multiparametric nonlinear regression analysis to estimate the binary coefficients and standard errors.
