Description :
The Literature reveals the extensive use of ultrasonic, thermodynamic and thermoacoustical parameters to characterize physico-chemical behavior of liquid mixtures and study the molecular interactions. In the present investigation an attempt has been made to evaluate and compare thermoacoustical parameters such as volume expansivity[α],Adiabatic compressibility[βa], Isothermal compressibility[βT], Molecular weight[M] Specific heat at constant pressure[Cp], Molar Volume[V],Reduced Volume [v̄ ],Characteristic volume[v*], Internal pressure[Pi], Intermolecular energy[Ф], Change in entropy[∆Ф] etc. of binary liquid mixtures cyclohexanol in methanol and cyclohexanol in cyclohexane for entire range of mole fraction. Experimental and computed results are used to study the type and nature of inter and intra molecular interactions between mixing components. The study of molecular interactions in liquid provides valuable information about internal structure, molecular association etc.
