Acoustical and Transport Behavior of Tetrapropylammonium Bromide in Binary Mixtures of N, N-Dimethylformamide and Ethylmethylketone at Different Temperatures
Abstract: Ultrasonic velocity, viscosity and density studies on solution of tetrapropyl ammonium bromide (Pr4NBr) have been carried out in N, N-dimethylformamide (DMF), ethylmethylketone (EMK) and DMF-EMK solvent mixtures containing 0, 20, 40, 60, 80 and 100 mol % of DMF at 298, 308 and 318K. From the velocity, viscosity and density data values, various parameters namely, the adiabatic compressibility (), Intermolecular free length (Lf), specific acoustic impedance (Z), free volume (Vf), internal pressure (i) and relaxation time () have been calculated. All these parameters have been discussed separately to throw light on the solute-solvent and solvent-solvent interactions.
