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 (V^E<inf>123</inf>) and speed of sound (u<inf>123</inf>) 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 303.15 K. The experimental speeds of sound data of the mixtures were used to calculate the deviation in isentropic compressibility (Δk<inf>s123</inf>). 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.
