Ultrasound techniques are unique and find wide applications and acceptance in all fields. Applications of ultrasonic have made possible not only the evaluation of physico-chemical properties of the mixtures/ solutions but also more reliability on the interpretation of molecular interactions. In view of the wide scope of molecular interactions between the highly polar compound of N-N-dimethylformamide with butylaminoethanol and 1-butylalcohol, ultrasonic velocity and densities have measured for these systems over the whole composition range at temperatures 293.15K, 298.15K, 303.15K, 308.15K and 313.15K under atmospheric pressure. To gain some insight into the several aggregations of molecular interactions present in these mixed solvents, deviation in ultrasonic velocity, excess acoustic impedance and excess pseudo Grüneisen parameter have been predicted. A qualitative analysis of the results is discussed in terms of the ion-dipole, ion-pair interactions, dispersive forces and hydrogen bonding prevailing in the binary mixtures. Further experimental data of these mixtures were also used to test the validity of various mixing rules/ theory for ultrasonic velocity.Keywords
