Density, speed of sound and viscosity of ethane-1,2-diol, methanol and methyl 4- hydroxybenzoate (methylparaben) at different concentrations and at constant temperature T=298K have been measured by Anton Paar DSA 5000 M density and velocity meter and Ostwald’s viscometer respectively. Experimentally measured values of density, speed of sound and viscosity are employed to calculate different ultrasonic parameters like impedance, adiabatic compressibility, intermolecular free length, acoustic attenuation, relaxation time, relative association, relative strength, and Gibb’s free energy. Graphs for each acoustical parameter against concentration are plotted with the help of Origin. The linear variation is found for most of the acoustic parameters which implies the absence of complex formation in ternary system studied.
