| Abstract: | The ultrasonic
velocities (U) and densities (r) are measured for solutions of biphenyl, thioanisole and
diphenylsulphide and mixtures containing equimolar concentrations of these
compounds and 1-chlorobenzotriazole (1-CBT) at 303 K in the concentration range
6 10-4-310-3 M.
Toluene was used as solvent for the biphenyl-1-CBT system and
1,4-dioxane was used as solvent for the other two systems. The coefficient of
viscosity ( ) values are determined for the mixtures
at 303 K. The acoustical parameters such as adiabatic compressibility ( ), free length (Lf),
relaxation time ( ) and free energy of activation ( G#) values are also
calculated. The trend in acoustical parameters indicate that there are
molecular interactions between the components and the formation of a charge
transfer complex between aromatic compound (donor) and 1-CBT (acceptor) is
established. |
