T3-phenyl-1-(2’,4’-difluorophenyl) prop-2-en-1-one was synthesized and
characterised by M.P., Infrared spectroscopy, Thin Layer Chromatography, and H1
NMR and GCMS data. The ultrasonic velocity, density and refractive indices of
mixed solvents (0-100% by wt.) of 3-phenyl-1-(2’,4’-difluorophenyl)
prop-2-en-1-one were measured at three different temperatures: 298, 303, and 308
K. The experimental data obtained was used to calculate various parameters such
as Molar volume (Vm), Free volume (Vf), Acoustical impedance (Z), intermolecular
free path length (Lf), adiabatic compressibility (), Rao’s molar sound velocity
(Rm), Relative association (Ra) Molar refraction (Rm), Specific refraction (r)
and Polarisability constant(a). These parameters are interpreted in terms of
solute- solute and solute- solvent interaction and its effect on mixed solvent
systems.
