摘要
The ultrasonic velocities (U), densities (r) and viscosities (h) of Binary mixture O-Chlorophenol +methyl salicylate, +ethyl salicylate and +benzyl salicylate from 303.15 to 318.15K. Excess molar volume (VE), deviation in adiabatic compressibility (Dbad) and excess inter molecular free length (LfE) have been calculated from the measured experimental data. The values of VE, Dbad, LfE and Dh have been fitted to Redlich-Kister polynomial equation to estimate binary coefficients and standard deviation between the experimental and computed values. Using Nomoto's relation (UNR), impedance relation (UIR), ideal mixing relation (Uimx), Junjie's relation (UJ), Rao's specific velocity relation (UR) and Kudriavtsev relation (UK), the theoretical ultrasonic velocities were evaluated. The computed estimations of ratio in velocity (U2/U2imx) from measured estimations of (U) are graphically shown. The molecular interaction parameter (a) has been evaluated. The validity of the theories were checked by calculating standard deviation and chi square test.
