Excess volume and isentropic compressibility study of ternary mixtures containing N-methylcyclohexylamine, chlorobenzene and 1-alkanols

Abstract

Excess volume (VE123) and speed of sound data for the ternary mixtures were reported at 303.15 K for the ternary mixtures containing N-methylcyclohexylamine and chlorobenzene as common components and 1-alkanols namely 1-propanol, 1-butanol or 1-pentanol were chosen as non-common components. The experimental data of speed of sound (u) and density (ρmix123) of mixture were used to compute isentropic compressibility (ks123) and the quantity (Δks123), the difference between measured value and that of computed from the constituent binary data. Further, the experimental ternary excess volume data were compared with predictive relations. The measured data were analysed on the basis of intermolecular interactions between component molecules and also in terms of constituent binary data.
