| 4 | Description | Abstract | The observed experimental parameters such as density (ρ), viscosity (η) and ultrasonic velocity (U) of ternary liquid mixtures of primary alkanols such as 1-propanol, 1-butanol, 1-pentanol and 1-hexanol with N-N dimethylfomamide (DMF) in acetophenone at 303.15 K were determined. The observed experimental data have been utilized to evaluate some of the thermo acoustical parameters and also their excess values such as adiabatic compressibility (ßE), intermolecular free length (LfE), free volume (VfE), internal pressure (πiE), Gibb’s energy (∇GEE) and viscosity (η E). Our present investigation observes that the interaction between DMF (Proton acceptor) and 1-alkanols is due to hydrogen bonding. There seems to be a dissociation of associated structure of 1-alkanols and decrease in interaction (hydrogen bonding) between acetophenone and 1-alkanols on further addition of DMF. It is also noticed that on further addition of DMF leads to subsequent decrease in interaction between ketone (acetophenone) and 1-alkanols as well as between DMF and 1-alkanol, which eventually resulting in existence of weak molecular interactions in the present system of liquid mixtures. |
