Abstract

The density, viscosity, surface tension and ultrasonic velocity have been measured in the binary mixture of gasoline with ethanol at five temperatures from 298.15 to 318.15K having difference of 5K. From these values the parameters like salvation number (Sn), relative association (RA), ultrasonic relaxation time ( u t ), dielectric relaxation time ( Di t ), excess adiabatic compressibility ( E ad b ), and excess volume (VE) have been calculated. These acoustic and thermodynamic parameters have been used to discuss the presence of significant interactions between the component molecules in the binary mixtures
