Abstract
In the current study, various thermodynamic and acoustical properties have been analyzed using density (ρ) and ultrasonic velocity (u) of liquid mixture aqueous glutaraldehyde with EG, DEG and TEG. It is carried out at different temperatures (293.15, 298.15, 303.15 and 308.15 K) and concentrations (0.01, 0.02, 0.03 and 0.04 mol.kg−1). Values of acoustic impendence (Z), adiabatic compressibility (β) and intermolecular free length (Lf) are calculated with the help of given velocity and density data. Adiabatic compressibility and intermolecular free length decreased with the rise in concentration, indicating weak interaction between the molecules of the mixture. Acoustic impedance varies linearly as concentration increases, indicating the absence of complex formation.
