| Abstract: | Ultrasonic velocity (U), density (ρ) and viscosity (η) have been measured of solutions
of all the four isomeric butyl alcohol in water at different mole fractions.
Acoustical parameters such as adiabatic compressibility (β), Rao constant(R), absorption coefficient (α/f2), internal pressure (πi),
cohesive energy (CE), free volume (Vf),
intermolecular free length (Lf)
and molecular interaction parameter with respect to velocity ( U)
were calculated from the experimental data. The intermolecular attraction
between the components depends on the mutual association of similar molecules
and their dissociation due to attraction between dissimilar molecules. The
strength of the bond depends on the length of the alkyl chain and the branching
in the alkyl group. The investigations also indicate that there are strong
intermolecular hydrogen bonds between alcohol and water molecules. |
