Volumetric, acoustic and FT-IR spectroscopic study on ternary and constituent binary mixtures containing N-methylcyclohexylamine, nitrobenzene and 1-alkanols at 303.15 K

Abstract

Excess volume (VE123) and speed of sound (u123) data for three ternary mixtures, containing N-methylcyclohexylamine and nitrobenzene as common components and 1-alkanols, namely, 1-propanol, 1-butanol or 1-pentanol as non-common component were reported at 303.15K. The experimental speeds of sound data of the mixtures were used to calculate the deviation in isentropic compressibility (Δks123). Further, experimental ternary excess volume data were compared with predictive relations in terms of Redlich–Kister, Kohler, Tsao–Smith and Hwang equations. Experimental results were analyzed on the basis of intermolecular interactions between component molecules with the help of FT-IR spectrum and also in terms of constituent binary mixtures.
