ULTRASONIC STUDY OF BINARY MIXTURES OF DHMOH AND ACETONE AT 288.15-313.15 K

The density (ρ), viscosity (η), and ultrasonic velocity (u) have been measured in the binary solutions of Dihydromyrcenol (DHMOH) with acetone at different temperatures: 288.15−313.15 K to understand the molecular interaction between these solutions. From the measured values, various acoustical parameters such as adiabatic compressibility (), acoustic impedance (Z), molecular free length (Lf), molar volume (Vm), free volume (Vf), Relative association (RA), internal pressure (i), and molar sound velocity (Um) were determined and correlated with concentration at different temperatures. The observed behaviour of these parameters concerning different compositions is discussed in terms of their molecular interactions between the unlike molecules of the binary solutions. The variations in measured and calculated values with concentration and temperature confirmed the presence of molecular interaction in the mixtures and were further confirmed by relative association.
