Ultrasonic studies on molecular interaction of a fragrant moiety with aprotic polar solvent in their binary mixtures

Ultrasonic study is an enabling technique for understanding the nature of molecular interactions in binary mixtures.Ultrasonic velocity (u), density (), and viscosity () for binary mixtures of dihydromyrcenol (DHMOH: a commercial fragrant entity) with acetone, bearing different molar concentrations were measured at the temperatures 298.15K, 303.15K, and 308.15K.The acoustic derived parameters such as adiabatic compressibility ( ), acoustic impedance (Z), intermolecular free length (Lf), and molar volume (Vm) were also determined.The effect of molar concentration and temperature variations on various parameters was taken into consideration.The measured values of ultrasonic velocity, density and viscosity were found to increase with the increase in concentration of the solute and decrease with increase in temperature.The chosen acoustic parameters revealed a strong relationship with both concentration and temperature of binary mixtures.
