Densities and refractive indices of ethyl acetate-isopropanol binary mixture

The density and refractive index of ethyl acetate-isopropanol mixture were measured at 293.15-318.15 K and atmospheric pressure.The data of density and refractive index were used to calculate the excess molar volumes and refractive index deviations,and correlated by Redlich-Kister equation respectively.The result shows that the excess molar volumes are positive and the refractive index deviations are negative over the whole mole fraction range,and both of deviations increase with temperature rise.The density data are fitted as a function of composition and temperature.The molar refractive index and its deviation of the binary system were calculated by Lorentz-Lorenz equation.The deviation increases with temperature rise.
