Acoustical and molecular interaction studies of amide with aliphatic amines in benzene at various temperatures
Abstract
The ultrasonic velocity, density and viscosity have been measured for the mixtures of amines,
namely, Di-methyl amine, Di-ethylamine and Tri-ethyl amine with amide in benzene at 303 K 313K
and 323K.The experimental data have been used to calculate the thermo dynamical parameters
namely adiabatic compressibility (β), free length (Lf), free volume (Vf) and internal pressure (Ài)
viscous relaxation time (Ä) and Gibbs’ free energy (ÃŽÂâ€G). Present study helped to find the existence
of strong molecular association. Such a molecular association is found to be by hydrogen bonding
and through dipole-dipole interaction
