Density (ρ), speed of sound (u) and viscosity (η) have been measured for the binary liquid mixtures of p-chloroacetophenone with n-propanol, n-butanol, n-pentanol at all temperature range from 303.15 K to 318.15 K. From this experimental data, excess molar volume (v E ), deviation in viscosity (∆η), deviation in isentropic compressibility (∆ks) and excess Gibbs energy of activation of viscous flow (G* E ) have been calculated and fitted to Redlich-Kister polynomial equation. These excess parameters, reveals that there is a strong interaction between the unlike molecules. The analyzed viscosity data of binary liquid mixtures were used to test the Grunberg-Nissan, Katti chaudari and Hind semi-empirical equations.

“…However, in contrast to benzene, the best correlation is found for the usage of (11) for cyclohexane and (7) for cyclohexene, but not for the T-H-E relation. Two additional short sets of data for T < T b give the triplets of AAD: (0.48, 2.68, 2.55) for (Cerdeiriña et al, 2001), and (1.60, 1.26, 0.54) for (Reddy et al, 2014). All these observations show that the speed of sound can be predicted using DIPPR data for cyclohexane and cyclohexene but the reason for the proper choice of the internal pressure equation needs some further investigations.…”

The paper analyses a possibility of utilising the information which is contained in DIPPR database for a calculation of the speed of sound, which is absent there. As an example, liquid hydrocarbons are considered: n-hexane, 1-hexene, cyclohexane, cyclohexene, benzene, and 1-hexanols, as well as representatives of n-alkanes with various hydrocarbon chain lengths. It is shown that the Brelvi-O'Connell correlation for the reduced bulk modulus, supplied with the correlations for the internal pressure at the normal boiling temperature, results in the values having accuracy comparable with other DIPPR data for the region below the boiling point bounded by the values of the reduced density around ρr ≈ 3.5. The source of errors originated from the Brelvi-O'Connell correlation for larger reduced densities is discussed.

“…Ultrasonic velocities of liquid mixtures containing polar and non-polar groups are of considerable importance in understanding intermolecular interaction between component molecules [1][2][3][4][5][6] . Comparative studies on the experimental theoretical values of ultrasonic velocities for various organic liquid mixtures using different theories/ models like Nomoto 7 , Impedance relation 8 , Van Dael and Vangael 9 , Junjie 10 and Rao's specific velocity 11 have been carried out by many researchers.…”

Ultrasonic velocities and densities of the binary liquid mixtures of ethyl lactate with o-xylene, m-xylene and p-xylene have been measured, over the entire composition range of mole fractions at different temperatures from 303.15 to 318.15 K with an interval of 5 K. The theoretical values of ultrasonic velocity were evaluated by using Nomoto (NOM), Impedance (IMP), Van Deal and Vangeel (VDV), Junjie's (JUN), Rao's specific velocity (RAO) models. The results are discussed in terms of non-ideality in the mixtures, molecular interaction parameter. Relative deviation σ and Chi-square (χ 2 ) test for the goodness of the fit was applied to understand the applicability of these theories to the present systems.
