Thermodynamic Properties of Phenetole with 2-Chlorophenol and 3-Chlorophenol at Different Temperatures

Authors(3) :-S. Arulappan, R. Raj Muhamed, R. Rajesh

Acoustical and excess thermo acoustical properties of 2-Chlorophenol (2-ChP), 3-Chlorophenol (3-ChP) with Phenetole in Tetrahydrofuran (THF) mixtures are investigated by measuring ultrasonic velocity (u), density (ρ) and viscosity (η) in different concentration range at atmospheric pressure at different temperatures. The trend in the acoustical parameters and magnitude of excess thermo acoustical parameters has been used to identify the existence of intra and intermolecular interaction through charge transfer complex formation. The formation of 1:1 complex was also confirmed by UV–Visible spectroscopic method at 303.15 K in these systems. It may be pointed out that the formation constants of the charge transfer complexes determined by Benesi–Hildebrand spectroscopic method and Kannappan equation in ultrasonic method. Thermodynamic parameters such as ΔG, ΔH and ΔS for these equilibria are determined.
