Abstract [English]

Alcohols have been investigated in 1,2-dichlorobenzene, butanone-2, and pentanone-2 at varying temperatures. We have examined the extent of molecular interaction in binary systems 1,2-dichlorobenzene + butanone-2 and 1,2-dichlorobenzene + pentanone-2 at varying temperatures of 303K, 308K, and 313K. Molecular interactions have been examined based on ultrasonic density and viscosity measurements. Additional thermodynamic parameters, including adiabatic compressibility, intermolecular free length, molar volume, available volume, shear relaxation time, specific acoustic impedance, and Rao’s constant, were calculated using measurements of ultrasonic velocity, density, and viscosity. The excess values of some thermodynamic functions indicate the existence of interactions within the component binary systems.
