Excess thermodynamic properties and FT-IR spectroscopic study of binary liquid mixtures of dichloro and trichlorobenzenes with 1-nonanol at T = (298.15, 303.15 and 308.15) K

Abstract

Excess volumes (VE), isentropic compressibilities (κs) and excess isentropic compressibilities (κsE) for the binary mixtures of {1,2-dichlorobenzene, 1,3-dichlorobenzene and 1,2,4-trichlorobenzene with 1-nonanol} at temperature range from 298.15 to 308.15K and at atmospheric pressure were derived from experimental density (ρ) and ultrasonic speed (u) data. The measured excess properties were correlated with the Redlich–Kister Polynomial equation. The calculated excess properties were discussed in terms of molecular interactions between dichloro/trichlorobenzenes and 1-nonanol molecules. Furthermore, the measured data were also analyzed with Fourier transform infrared (FT-IR) spectroscopy since FT-IR is a powerful tool to get information regarding the existence of molecular interactions between component molecules.
