The study of molecular interaction in organic liquid mixture plays an important role in the development of molecular science. The present investigation deals with the study of Lennard Jones potential repulsive term exponent, relative association and interaction parameter to explain molecular interaction in binary liquid mixture of an aprotic liquid dimethyl acetamide (DMAC) with isobutyl methyl ketone at different frequencies and at constant temperature 308K.The study of DMAC is important because of its utilization in industry and pharmaceuticals. Ultrasonic velocity (U) and density (ρ) of the binary liquid mixture at different frequencies 2 MHz, 4 MHz, 6 MHz and 8MHz have been measured at temperature 308 K. Lennard Jones potential repulsive term exponent (n) relative association (RA) and interaction parameter (χ) have been calculated for the entire range of mole fraction and are interpreted to explain molecular interaction occurring in the liquid mixture.Keywords

The ultrasonic velocity density and coefficient of viscosity of the ternary mixture of dimethyl acetamide, isobutyl methyl ketone and diethyl ether at frequencies 2MHz, 4MHz, 6MHz and 8MHz have been measured at temperature 308K. Adiabatic compressibility, intermolecular free length, free volume, internal pressure and their respective excess values have been computed for entire range of mole fraction and are interpreted to explain molecular interaction occurring in the liquid mixture. Relaxation time, excess enthalpy and absorption coefficient have been calculated and discussed. The negative excess values of coefficient of viscosity indicate the presence dispersion, induction and dipolar forces in ternary liquid mixture.The negative values of excess adiabatic compressibility, excess free length, excess free volume and excess enthalpy and the positive values of excess internal pressure indicate the presence of specific interactions in the ternary liquid mixture.Keywords

Ultrasonic velocity (U), density (ρ) and coefficient of viscosity (η) in aprotic-aprotic binary mixture of acetyldimethylamine and isobutyl methyl ketone at different frequencies have been measured at constant temperature 308 K.
