Density, Speed of Sound, and Refractive Index of the Binary Systems Cyclohexane (1) or Methylcyclohexane (1) or Cyclo-octane (1) with Benzene (2), Toluene (2), and Ethylbenzene (2) at Two Temperatures

Abstract

Densities, speeds of sound, and refractive indices of binary systems containing cycloalkanes (cyclohexane and methylcyclohexane) with aromatic compounds (benzene, toluene, and ethylbenzene) at T = (283.15 and 298.15) K and cyclo-octane with aromatic compounds at T = 298.15 K under atmospheric pressure were determined over the whole composition range. From the experimental results, the derived and excess properties (excess molar volumes, isentropic compression, excess molar isentropic compressibility, and refractive index deviations) at T = (283.15 and 298.15) K were calculated and satisfactorily fitted to the Redlich−Kister equation.
