“…Several researches [5][6][7][8][9] have studied the complexes of alcohols with ketones, amides, esters, nitriles and amines using ultrasonic velocity measurements. The investigation regarding the molecular association in organic ternary mixtures having alcohol as one of the components is of particular interest, since alcohols are highly polar and self associated through hydrogen bonding in pure state [10] .…”

Abstract:The ultrasonic velocity, density and viscosity measurements were carried out for the mixtures of benzamide with Propan-2-ol, butan-1-ol, 1-pentanol and n-hexanal in 1,4-dioxan at 303, 308 and 313K. The derived acoustic and thermodynamic parameters namely adiabatic compressibility, free length, free volume, internal pressure, viscous relaxation time and Gibbs free energy were evaluated with a view to investigate the nature of molecular interaction.The obtained results support the occurance of complex formation through intermolecular hydrogen bonding in these ternary liquid mixtures.

“…The same trend is absorbed in free length also. The change of free volume as mole fraction changes shows that at a particular concentration of 0.5 free volume is maximum which indicates the association [ 5 ] of the molecules in the solution. This is also absorbed in the case of internal pressure in the reverse manner.…”

“…[1][2][3][4] which is very much useful to study the interactions and structural aspect of liquid mixtures. Several DOI: 10.1002/masy.202200006 researches [5][6][7][8][9] investigate the molecular association in organic binary mixtures having alcohol which are highly polar and selfassociated through hydrogen bonding in pure state. [10] The mono alcohols are much studied system for the simple reasons that they are biologically important, that their self-association is interestingly complicated and that they form hydrogen bonds with ketones, amines, esters and other proton acceptors.…”

In this present work, the molecular interaction of the binary liquid mixture has been elucidated using ultrasonic technique. The recorded values of ultrasonic velocity (u), density (𝝆), viscosity (𝜼), and refractive index (n) for the experimented binary liquid mixtures of Ethanol with Benzene at 303 K are used to calculate the derived parameters such as adiabatic compressibility (𝜷 a ), free length (L f ), acoustic impedance (Z), free volume (V f ), molar volume (V m ), internal pressure (𝝅 i ), relaxation time (𝝉), Enthalpy (H), Electronic polarization (𝝐), Molar refraction (R m ), and the experimentally determined ultrasonic velocity have been compared with the with the computed values using different analytical models and empirical relations such as Nomoto's Theory (NOM), Free Length Theory (FLT), and Van Dael-Vangeal theory (VDV). The results are interpreted and reported to explain the behavior of benzene with ethanol.
