“…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.

“…Previous investigations have been carried out on p-chloroacetophenone [3][4][5] and anilines [6][7][8][9] and amines [10,11] have been reported. Literature survey shown that no work has been executed on p-chloroacetophenone and aniline, N-methylaniline and N,N-dimethylaniline at 303.15 to 318.15 K. The effect of molecular size, chain length, shape and extent of molecular association of aromatic and aliphatic amines on volumetric, viscometric and acoustic properties of binary liquid mixtures containing hydrocarbons, esters and alcohols have been studied earlier [12][13][14][15][16][17][18].…”

Ultrasonic velocities (u), viscosities (η) and densities (ρ) were measured for the binary mixtures of p-chloroacetophenone with aniline, N-methylaniline and N,N-dimethylaniline over the whole range of composition at different temperatures (303.15 K to 318.15 K) and at atmospheric pressure 0.1 MPa. Excess molar volume (V E ), deviation in viscosity (∆η) and deviation in isentropic compressibility (∆ks) have been calculated and fitted to Redlich-Kister polynomial equation to obtain their coefficients and standard deviations. The analyzed viscosity data of binary liquid mixtures were used to test the Grunberg-Nissan, Katti-Chaudari and Hind semi-empirical equations. The FTIR spectral study supports the experimental data to explain the molecular interactions between unlike molecules. Partial molar volumes of binary mixtures were evaluated for better understanding of intermolecular interactions of the above binary mixtures.This is an open access journal, and articles are distributed under the terms of the Attribution 4.0 International (CC BY 4.0) License.

“…We reported in our earlier communications [5, 6] excess volumes, sound velocities and viscosities for the binary mixtures of N -ethyl aniline and N , N -dimethyl aniline with aromatic ketones. A survey of literature has shown that thermodynamic properties of amines with 2-propanone, 2-butanone and 2-pentanone were reported [7–9].…”

Densities, ρ, viscosities, η, and ultrasonic sound velocities u of pure methyl isobutylketone, diethylketone, cyclopentanone, cyclohexanone, 2-methyl cyclohexanone and those of their binary mixtures with N-methyl aniline were measured at 303.15 K over the entire composition range. These experimental data have been used to calculate the excess volume (VE), deviation in ultrasonic sound velocity (∆u), isentropic compressibility (κs), intermolecular free length (Lf), excess intermolecular free length (), acoustic impedance (Z), excess isentropic compressibility (), deviation in viscosity (∆η) and excess Gibbs energy of activation of viscous flow (G*E). The viscosity data have been correlated using three equations proposed by Grunberg and Nissan, Katti and Chaudhri, and Hind et al. The excess/deviations have been fitted by Redlich–Kister equation and the results are discussed in terms of molecular interactions present in these mixtures.
