Refractive indices of binary liquid mixtures of (decanc plus benzene) and (hexadecane plus benzene, or plus hexane) at 303.15, 308.15 and 313.15 K

Refractive indices at 303.15, 308.15 and 313.15K have been measured for the binary liquid mixtures of (decane + benzene), and (hexadecane + benzene, or + hexane) over the entire composition range, From the experimentally measured values, refractive index deviations at different temperatures have been computed and fitted to the Redlich-Kister polynomial equation to derive the binary coefficients and standard errors, Using various mixing rules, refractive indices of the binary liquid mixtures at 298.15K have been calculated theoretically and the results discussed in terms of average percentage deviations.
