Ultrasonic Studies of Molecular Interaction of Alcohols With Non-Polar Solvents

Abstract

In the carbon tetrachloride / benzene method, dimethylketone measured ultrasound velocity, density and viscosity at 301 K of alcohol mixtures (pentanol, hexanol, heptanol, octanol and decanol).The following acoustical parameter was assessed from the measured values. The potential of adiabatic compression, acoustic impedance, relaxation time, relative intermolecular interlinkage with free length, free volume, available volume, constant Wadas and Rao's, Linard-John. In liquid mixtures, the essence of intermolecular interaction was dependent on the variance of the acoustic parameter.The interaction of non-polar molecules is decreasing as the length of the alcohol chains increases. Effects of molecular interactions, including dipole-dipole interaction through hydrogen bonds between solvents and 1-alkanols, were studied and interpreted. In addition, the experimental ultrasound speeds for all these binary systems are compared to the theoretical ultrasound speed
