Acoustical Parameters of Some Binary Liquid Mixtures Containing Heterocyclic Aromatic Compound with Methylphenols at Different Temperatures

Abstract

Ultrasonic velocity (u), density (r) and viscosity (h) values have been measured in the three binary mixrures containing heterocyclic aromatic compound such as quinoline with 2,3,4-methylphenols such as o-cresol, m-cresol, p-cresol respectively at 303.15K, 308.15K, 313.15K and 318.15K. From this data, acoustical parameters such as adiabatic compressibility (b), free length (L_f), free volume (V_f) and internal pressure (p) have been estimated using standard relations.These parameters are useful for explaining the molecular association between the components of liquid mixtures.
