Excess compressibility and excess volume studies in the binary mixtures of methyl and ethyl acetate in O-chlorophenol at different temperatures

Abstract

Ultrasonic velocity and density measurements have been carried out in the binary mixtures of methyl acetate (MA) and ethyl acetate (EA) in O-chlorophenol (OCP) at 303.15, 308.15, 313.15, 318.15 and 323.15 K. From the experimental data, the excess thermodynamical parameters such as excess adiabatic compressibility (β), excess intermolecular free length (L) and excess molar volume (V^E) have been calculated. The results have been interpreted in terms of intermolecular interactions leading to complex formation through the formation of hydrogen bonds between the component molecules of the mixture.
