Study of Binary Liquid Mixtures of Cyclohexane with Glycols and Polyglycols at 308.15 K Using Sound Velocities

ABSTRACT

and polyglycols (polyethylene glycol -200 [PEG-200], PEG-400 and polyethylene-600 [PEG-600]) are used to study the interactions between molecules by measuring the densities and sound velocities at 308.15 K. Functions like excess ultrasonic velocity (uE), excess Isentropic compressibility ( KSE ), excess Intermolecular free length ( LfE ), and excess acoustic impedance
(ZE) for the binary liquid mixtures under study have been calculated from the measured data. These excess function values werefitted to the Redlich–Kister polynomial equation. The nature and extent of intermolecular interactions between the componentsare discussed from the results and are found to be in the following order CH + EG < CH + DEG < CH + TEG < CH + PEG-200< CH + PEG-400 < CH + PEG-600.

Key words: Ultrasonic velocity, Cyclohexane, Ethylene glycols, Poly (ethylene glycols), Isentropic compressibility,Intermolecular free length, Acoustic impedance.
