Acoustic Study of Intermolecular Interactions in Bi nary Liquid Mixtures
Abstract The ultrasonic velocity, density and viscosity have been measured for the binary mixtures of 1-propanol with toluene, benzene and cyclohexane at 303K The experimental data have been used to calculate the acoustical parameters namely adiabatic comprehensibility ( β ), free length (L f ), free volume (V f ), internal pressure ( π i ), acoustic impedance (Z) and molar volume(V m ). The excess values of some the above parameters are also evaluated and presented. A weak molecular interaction between the component molecules is observed in the present investigation. Also, the addition of non-polar component with polar 1-propanol causes dissociation of its hydrogen bonded structure. A weak magnitude of molecular association is observed in 1-prpoanol-cyclohexane system For more info: http://www.jocpr.com/articles/acoustic-study-of-intermolecular-interactions-in-binary-liquid-mixtures.pdf
