Excess thermodynamic and spectroscopic study of ternary mixtures containing N-methylcyclohexylamine, bromobenzene, and 1-alkanols at 303.15 K

Abstract

Excess volume and sound speed data for three ternary mixtures, containing N-methylcyclohexylamine and bromobenzene as common components and 1-alkanols such as 1-propanol, 1-butanol, and 1-pentanol as third component, were measured at 303.15 K over the entire composition range. The experimental speeds of sound were used to compute isentropic compressibility and deviation in isentropic compressibility. The excess volume data of all mixtures were compared with data obtained from predictive expressions due to Redlich–Kister, Kohler, Tsao–Smith, and Hwang et al.’s equations. Further, the experimental results were analyzed in terms of molecular interactions between component molecules with FT-IR spectrum. Excess volume and speed of sound measured at 303.15 K for three ternary mixtures containing N-methylcyclohexylamine (1), bromobenzene (2), and 1-alcohols (3). Results were used to calculate derived thermodynamic properties and analyzed in terms of intermolecular interactions between component molecules.
