“…The compressibility dependences on composition for diluted alcohols in n-propanol are linear. However, they are not linear for solutions in n-heptane, as already reported by Kiyohara and Benson [10]. This behavior has not been deeply investigated nor satisfactorily explained yet.…”

The method of Passynski of calculating the solvation numbers from compressibility was applied to solutions of short-chained normal alcohols in n-heptane and n-propanol. The dependences of solvation numbers on length of the solute molecules are surprisingly similar for both solvents. Applicability of the acoustic method for determining the solvation numbers in nonaquous systems, as well as for investigation of intermolecular interactions in them was proved. Some structural similarity of associated alcohol and hydrocarbon in liquid state is suggested.

“…The negative deviation in compressibility for all the three systems studied indicate the existence of strong interaction between the unlike molecules. [48][49] The diversity in viscosity (∆η) gives a quantitative estimate of intermolecular interactions. The ∆η at each composition is obtained from the relation suggested by Fort and Moore 50 .…”

Density (ρ), ultrasonic velocities (u) and dynamic viscosity (η) for three binary clusters of Trichloroethylene with 1-pentanol, 1-hexanol and 1-heptanol are experimented at ambient temperature 303.15K at atmospheric pressure over various compositions. The density and viscosity are calibrated using Specific gravity bottle and Ostwald's glass capillary viscometer respectively. The velocity is measured using ultrasonic interferometer. Molar volume, adiabatic compressibility, Intermolecular free length, and Wada's Constant are calculated using the above measured values. The excess parameters viz., excess molar volume, excess adiabatic compressibility, excess intermolecular free length, viscosity deviation are also deducted from experimental values. Intermolecular interactions, and structural interactions present in various mixture are discussed in detail.

“…The negative deviation in isentropic compressibility for all the three systems at all temperatures as shown in Figure 2 and Table 4-7 ∆ks values indicates the packing is highly efficient than in the pure components and the presence of strong intermolecular bonding between the components in the binary mixture 13 . There are stronger interactions for the PCAP + n-Propanol system.…”

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.
