Densities, refractive indices, and derived excess properties of the binary systems toluene plus isooctane and methylcyclohexane plus isooctane and the ternary systems tert-butyl alcohol plus toluene plus isooctane and tert-butyl alcohol plus methylcyclohexane plus isooctane at 298.15 K

This paper reports mesurements of the densities and refractive indices of the binary systems toluene + isooctane and methylcyclohexane + isooctane and the ternary systems tert-butyl alcohol (TBA) + toluene + isooctane and tert-butyl alcohol (TBA) + methylcyclohexane + isooctane over the entire range of composition at 298.15 K. Excess molar volumes and changes of refractive indices were evaluated from the experimental data obtained. These derived properties were fitted to variable-degree polynomials. The experimental values of physical properties were compared with the values estimated by different methods.
