Thermo-acoustic and FTIR studies on binary liquids mixture of ethyl oleate and benzaldehyde at 303.15 to 318.15 K.

Ultrasonic velocity, density and viscosity of two liquid mixtures ethyl oleate with benzaldehyde have been determined at various temperatures in the range of 303.15 to 318.15 K. The ultrasonic velocity, viscosity and density data are used to estimate adiabatic compressibility, free length, molar volume and free volume along with their excess values. The observed variations of the said parameters with concentration and temperature are discussed in terms of the intermolecular interactions between the unlike molecules of the binary mixtures. FT-IR spectra confirm the expected interactions.
