Thermoacoustical studies on the Binary mixtures of Methyl and Ethyl acetate (MA & EA) in 2-Methoxyethanol (2ME) at different temperatures

Density and ultrasonic velocity have been measured in the binary liquid mixtures of methyl acetate (MA) and ethyl acetate (EA) in 2-methoxyethanol (2ME) over the temperature range from 303.15 to 323.15 K. The measured data are used to compute the excess thermodynamic parameters namely excess adiabatic compressibility (βs E ), excess intermolecular free length (Lf E ) and excess molar volume (V E ). A plot of these excess thermodynamic parameters against the mole fraction of methyl acetate and ethyl acetate over the entire composition range shows a negative deviation indicating a strong interaction between the component molecules of liquid mixtures. The results are discussed in terms of formation of hydrogen bonding between the component molecules of the liquid mixtures.
