Prediction of Refractive Indices of Some Binary Liquid Mixtures of Containing 1,3-Dioxolane with Alkanols (c5-c10) at 298.15k

Density (ρ), viscosity (η) and refractive indices (n) of the binary mixture between 1,3-Dioxolane with pentanol. hexanol, heptanol, octanol, nonanol and decanol for the entire concentration range have been measured at 298.15K, furthermore, deviation in refractive indies from ideal mixture for this mixture has also been evaluated.The determination of light refractive index is an important step in the characterization of liquid mixtures with different industrial applications. Through it, the purity of their substances can be assessed and, together with density andultrasonic velocities, it has a significant role in characterizing and understanding the thermodynamic properties of the liquids.The results are presented in terms of excess refractive indices from the experimental values.The deviations from ideality of the refractive indies are explained on the basis of molecular interaction between the component molecules in these binary liquid mixtures.
