Molecular Interaction study of Curcumin with 1-Propanol binary mixture

摘要

ABSTRACT Ultrasonic velocity, density and viscosity of binary mixtures of Curcumin and 1-Propanol have been measured at room temperature 303K. Using the measured velocity the thermodynamic parameters such as adiabatic compressibility (), inter molecular free length (Lf), Acoustic impedance (Z), free volume (VE) have been calculated. It has been established that ultrasonic velocity decreases with increasing the mole fraction. The results show a nonlinear variation of acoustical parameters confir.
