Molecular Interaction Studies in Ternary Liquid Mixtures Containing 2-Nitroanisole and 1- Pentanol in n- Hexane at Different Temperatures using Ultrasonic Techniques

Abstract

The experimental values of ultrasonic velocity, density and viscosity have been measured for the ternary liquid mixtures containing 2-Nitroanisole and 1-Pentanol in n-Hexane at 303,308 and 313K. To calculate various acoustical parameters like adiabatic compressibility, free volume, internal pressure, acoustical impedance, adsorption co-efficient and molecular interaction parameters have been computed using the experimental data. The linearity of variation in ultrasonic velocity and other parameters are due to the molecular interaction between donor acceptor molecules in liquid-liquid mixture. The various molecular interactions like dipole-dipole, dipole-induced dipole, induced-induced dipole have been discussed for the liquid mixture containing 2-Nitroanisone, 1-Pentanol in n-Hexane at different temperatures and concentration.
