Abstract

Binary liquid mixtures find practical applications in most physical and chemical processes. Derived
parameters from ultrasonic velocity measurement provide qualitative information regarding the
nature and strength of interactions in liquid mixtures. The ultrasonic velocity, density and viscosity
have been measured for the binary liquid mixture of Diethyl ether with pesticide (methyl parathion)
at 303K and 308K. The experimental data have been used to calculate the acoustical parameters
namely isentropic compressibility, intermolecular free length, free volume, specific acoustic
impedance and shears relaxation time. These parameters have been discussed in the light of
molecular interaction present in the mixture.
Keywords: Pesticides, Acoustical parameters, Molecular interaction.
