Ultrasonic Investigation of Thermodynamic Parameters in Binary Liquid Mixture of Acetonitrile in 2- Propanol at 301.15K

The ultrasonic velocity (u), density (ρ) and viscosity (η) related thermo-acoustic parameters are the important tools in understanding nature extent of pattern molecular interactions between components liquid mixture. velocity, viscosities binary mixture containing Acetonitrile 2- Propanol over whole concentration range have been measured at 305.15K. This data used to compute derived like adiabatic compressibility (βad), free length (Lf)), volume (Vf), internal pressure (πi), acoustic impedance (Z). variation these with temperature also correlate structural changes observed Keywords: Binary mixture, (η), (Lf), (Vf),internal molar volume(Vm).
