The ultrasonic velocity, density and viscosity of binary liquid mixtures of lactic acid with methanol, 1-propanol and 2- propanol of various compositions at 308 K, 313 K, 318 K and 323 K were determined. These experimental data have been used to estimate the thermodynamic parameters such as adiabatic compressibility (β),free length (L f ), free volume (V f ), internal pressure (π i )and enthalpy (H). The excess values of the above parameters like excess adiabatic compressibility, excess free length, excess free volume, excess internal pressure and excess enthalpy are also evaluated in order to dispute the nature of molecular interactions present among the constituent molecules of binary liquid mixture systems.Keywords

Thermodynamic parameters like adiabatic compressibility, free length, acoustic impedance, internal pressure and enthalpy of curcumine with three different alcohol at 308 K, 313 K, 318 K and 323 K temperature and different concentration is determined by using ultrasonic technique. The results are explained in terms of intermolecular interaction between the components in the binary liquid mixture.Keywords
