The ultrasonic velocities U, densities ρ of Binary Mixtures of O - Chlorophenol with 1- hexanol, 1- heptanol and 1- octanol
from 303.15 to 318.15K. Excess molar volume (VE), deviation in adiabatic compressibility (Δβad) and excess
intermolecular free length (LfE) have been calculated from the measured experimental data. The values of VE, Δβad and LfEhave been tted to
Redlich – Kister polynomial equation to estimate binary coefcients and standard deviation between the experimental and computed values.
The ultrasonic velocities (U), densities (ρ) and viscosities (η) 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 (Δβad) and excess inter molecular free length (LfE) have been calculated from the measured experimental data. The values of VE, Δβad, LfE and Δη 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 (α) has been evaluated. The validity of the theories were checked by calculating standard deviation and chi square test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
